5eab0a3cb2 Tests: Increase nomodule test timeout for IE from 1s to 5s
In IE, these tests are expected to be executed, so the timeout can be higher,
similar to how we set a high timeout for module tests.

5964acf330 Tests: Fix module/nomodule tests flakiness
The module/nomodule tests are the most flaky ones, contributing significantly
to increase number of test failures (somewhat mitigated by auto-retries).

Fix flakiness of module/nomodule tests:
1. For module tests, increase the timeout to 5 seconds. In order for most tests
   to not wait that long, change callbacks called by module scripts to verify
   the results as soon as all scripts have run.
2. For nomodule tests, run the check in 1 second. All modern browsers will
   need to wait that long, hence a smaller timeout, and if occasionally the
   check runs too quickly, the test will still pass.

3a31866b80 Tests: Backport the hidden="until-found" attr tests from 3.x-stable
The `hidden` attribute used to be a boolean one but it gained a new
`until-found` eventually. This led us to change the way we handle boolean
attributes in jQuery 4.0 in gh-5452 to avoid these issues in the future.

We haven't added an explicit test for the `"until-found"` value of the
`hidden` attribute which triggered this decision so far, though.
Backport the test from gh-5607 which landed on `3.x-stable` so that we
do test it.

eca2a56457 CSS: Fix dimensions of table <col> elements
Changes:
1. Fix measurements of `<col span="2">` elements in Firefox.
2. Fix measurements of all implicitly sized `<col>` elements in Safari.

Firefox always reports computed width as if `span` was 1. In Safari, computed
width for columns is always 0. Work around both issues by using `offsetWidth`.

In IE/Edge, `<col>` computed width is `"auto"` unless `width` is set explicitly
via CSS so measurements there remain incorrect. Because of the lack of a proper
workaround, we accept this limitation.

4466770992 Tests: Add custom attribute getter tests to the selector module
Sizzle & the `3.x-stable` branch have tests adding a custom attribute getter
to `attrHandle` and checking if selection takes it into account. `attrHandle`
was removed from the `4.x` line so the tests were not ported to the `main`
branch, but the `4.x` line takes standard jQuery attribute getters into account
instead and we should test for that.

Backport the `3.x-stable` selector tests for custom attribute getters, changing
`jQuery.expr.attrHandle` to `jQuery.attrHooks`.

640d5825df CSS: Drop the cache in finalPropName
The `finalPropName` util caches properties detected to require a vendor
prefix. This used to cache unprefixed properties as well, but it was
reported that this logic broke accidentally during a refactor. Since
fewer & fewer properties require a vendor prefix and caching a few
basic checks likely has negligible perf benefits, opt to saving a few

527fb3dcf0 Event: Increase robustness of an inner native event in leverageNative
In Firefox, alert displayed just before blurring an element dispatches
the native blur event twice which tripped the jQuery logic if a jQuery blur
handler was not attached before the trigger call.

This was because the `leverageNative` logic part for triggering first checked if
setup was done before (which, for example, is done if a jQuery handler was
registered before for this element+event pair) and - if it was not - added
a dummy handler that just returned `true`. The `leverageNative` logic made that
`true` then saved into private data, replacing the previous `saved` array. Since
`true` passed the truthy check, the second native inner handler treated `true`
as an array, crashing on the `slice` call.

The same issue could happen if a handler returning `true` is attached before
triggering. A bare `length` check would not be enough as the user handler may
return an array-like as well. To remove this potential data shape clash, capture
the inner result in an object with a `value` property instead of saving it
directly.

Since it's impossible to call `alert()` in unit tests, simulate the issue by
replacing the `addEventListener` method on a test button with a version that
calls attached blur handlers twice.

063831b637 Attributes: Make .attr( name, false ) remove for all non-ARIA attrs
The HTML spec defines boolean attributes:
https://html.spec.whatwg.org/#boolean-attributes
that often correlate with boolean properties. If the attribute is missing, it
correlates with the `false` property value, if it's present - the `true`
property value. The only valid values are an empty string or the attribute name.

jQuery tried to be helpful here and treated boolean attributes in a special way
in the `.attr()` API:
1. For the getter, as long as the attribute was present, it was returning the
   attribute name lowercased, ignoring the value.
2. For the setter, it was removing the attribute when `false` was passed;
   otherwise, it was ignoring the passed value and set the attribute -
   interestingly, in jQuery `>=3` not lowercased anymore.

The problem is the spec occasionally converts boolean attributes into ones with
additional attribute values with special behavior - one such example is the new
`"until-found"` value for the `hidden` attribute. Our setter normalization
means passing those values is impossible with jQuery. Also, new boolean
attributes are introduced occasionally and jQuery cannot easily add them to the
list without incurring breaking changes.

This patch removes any special handling of boolean attributes - the getter
returns the value as-is and the setter sets the provided value.

To provide better backwards compatibility with the very frequent `false` value
provided to remove the attribute, this patch makes `false` trigger attribute
removal for ALL non-ARIA attributes. ARIA attributes are exempt from the rule
since many of them recognize `"false"` as a valid value with semantics different
than the attribute missing. To remove an ARIA attribute, use `.removeAttr()` or
pass `null` as the value to `.attr()` which doesn't have this exception.

dfc693ea25 Tests: migrate testing infrastructure to minimal dependencies
This is a complete rework of our testing infrastructure. The main goal is to modernize and drop deprecated or undermaintained dependencies (specifically, grunt, karma, and testswarm). We've achieved that by limiting our dependency list to ones that are unlikely to drop support any time soon. The new dependency list includes:

- `qunit` (our trusty unit testing library)
- `selenium-webdriver` (for spinning up local browsers)
- `express` (for starting a test server and adding middleware)
  - express middleware includes uses of `body-parser` and `raw-body`
- `yargs` (for constructing a CLI with pretty help text)
- BrowserStack (for running each of our QUnit modules separately in all of our supported browsers)
  - `browserstack-local` (for opening a local tunnel. This is the same package still currently used in the new Browserstack SDK)
  - We are not using any other BrowserStack library. The newest BrowserStack SDK does not fit our needs (and isn't open source). Existing libraries, such as `node-browserstack` or `browserstack-runner`, either do not quite fit our needs, are under-maintained and out-of-date, or are not robust enough to meet all of our requirements. We instead call the [BrowserStack REST API](https://github.com/browserstack/api) directly.

## BrowserStack Runner
- automatically retries individual modules in case of test failure(s)
- automatically attempts to re-establish broken tunnels
- automatically refreshes the page in case a test run has stalled
- runs all browsers concurrently and uses as many sessions as are available under the BrowserStack plan. It will wait for available sessions if there are none.
- supports filtering the available list of browsers by browser name, browser version, device, OS, and OS version (see `npm run test:unit -- --list-browsers` for more info). It will retrieve the latest matching browser available if any of those parameters are not specified.
- cleans up after itself (closes the local tunnel, stops the test server, etc.)
- Requires `BROWSERSTACK_USERNAME` and `BROWSERSTACK_ACCESS_KEY` environment variables.

## Selenium Runner
- supports running any local browser as long as the driver is installed, including support for headless mode in Chrome, FF, and Edge
- supports running `basic` tests on the latest [jsdom](https://github.com/jsdom/jsdom#readme), which can be seen in action in this PR (see `test:browserless`)
- Node tests will run as before in PRs and all non-dependabot branches, but now includes tests on real Safari in a GH actions macos image instead of playwright-webkit.
- can run multiple browsers and multiple modules concurrently

Other notes:
- Stale dependencies have been removed and all remaining dependencies have been upgraded with a few exceptions:
  - `sinon`: stopped supporting IE in version 10. But, `sinon` has been updated to 9.x.
  - `husky`: latest does not support Node 10 and runs on `npm install`. Needed for now until git builds are migrated to GitHub Actions.
  - `rollup`: latest does not support Node 10. Needed for now until git builds are migrated to GitHub Actions.
- BrowserStack tests are set to run on each `main` branch commit
- `debug` mode leaves Selenium browsers open whether they pass or fail and leaves browsers with test failures open on BrowserStack. The latter is to avoid leaving open too many sessions.
- This PR includes a workflow to dispatch BrowserStack runs on-demand
- The Node version used for most workflow tests has been upgraded to 20.x
- updated supportjQuery to 3.7.1

Run `npm run test:unit -- --help` for CLI documentation

6ad3651dbf Event: Make trigger(focus/blur/click) work with native handlers
In `leverageNative`, instead of calling `event.stopImmediatePropagation()`
which would abort both native & jQuery handlers, set the wrapper's
`isImmediatePropagationStopped` property to a function returning `true`.
Since for each element + type pair jQuery attaches only one native handler,
there is also only one wrapper jQuery event so this achieves the goal:
on the target element jQuery handlers don't fire but native ones do.

Unfortunately, this workaround doesn't work for handlers on ancestors
- since the native event is re-wrapped by a jQuery one on each level of
the propagation, the only way to stop it for jQuery was to stop it for
everyone via native `stopPropagation()`. This is not a problem for
`focus`/`blur` which don't bubble, but it does also stop `click` on
checkboxes and radios. We accept this limitation.

ce60d31893 Event: Simulate focus/blur in IE via focusin/focusout
In IE (all versions), `focus` & `blur` handlers are fired asynchronously
but `focusin` & `focusout` are run synchronously. In other browsers, all
those handlers are fired synchronously. Asynchronous behavior of these
handlers in IE caused issues for IE (gh-4856, gh-4859).

We now simulate `focus` via `focusin` & `blur` via `focusout` in IE to avoid
these issues. This also let us simplify some tests.

This commit also simplifies `leverageNative` - with IE now using `focusin`
to simulate `focus` and `focusout` to simulate `blur`, we don't have to deal
with async events in `leverageNative`. This also fixes broken `focus` triggers
after first triggering it on a hidden element - previously, `leverageNative`
assumed that the native `focus` handler not firing after calling the native 
`focus` method meant it would be handled later, asynchronously, which
was not the case (gh-4950).

258ca1ec6a Deferred: Rename getStackHook to getErrorHook
Rename `jQuery.Deferred.getStackHook` to `jQuery.Deferred.getErrorHook`
to indicate passing an error instance is usually a better choice - it
works with source maps while a raw stack generally does not.

In jQuery `3.7.0`, we'll keep both names, marking the old one as
deprecated. In jQuery `4.0.0` we'll just keep the new one. This
change implements the `4.0.0` version; PR gh-5212 implements
the `3.7.0` one.

68aa2ef757 Selector: Stop relying on CSS.supports( "selector(...)" )
`CSS.supports( "selector(...)" )` has different semantics than selectors passed
to `querySelectorAll`. Apart from the fact that the former returns `false` for
unrecognized selectors and the latter throws, `qSA` is more forgiving and
accepts some invalid selectors, auto-correcting them where needed - for
example, mismatched brackers are auto-closed. This behavior difference is
breaking for many users.

To add to that, a recent CSSWG resolution made `:is()` & `:where()` the only
pseudos with forgiving parsing; browsers are in the process of making `:has()`
parsing unforgiving.

Taking all that into account, we go back to our previous try-catch approach
without relying on `CSS.supports( "selector(...)" )`. The only difference
is we detect forgiving parsing in `:has()` and mark the selector as buggy.

The PR also updates `playwright-webkit` so that we test against a version
of WebKit that already has non-forgiving `:has()`.

2e644e8450 Selector: Backport jQuery selection context logic to selector-native
This makes:
```js
$div.find("div > *")
```
no longer matching children of `$div`.

Also, leading combinators now work, e.g.:
```js
$div.find( "> *" );
```
returns children of `$div`.

As a result of that, a number of tests are no longer skipped in the
`selector-native` mode.

Also, rename `rcombinators` to `rleadingCombinator`.

a7ed9a7b63 Ajax: Support binary data (including FormData)
Two changes have been applied:
* prefilters are now applied before data is converted to a string;
  this allows prefilters to disable such a conversion
* a prefilter for binary data is added; it disables data conversion
  for non-string non-plain-object `data`; for `FormData` bodies, it
  removes manually-set `Content-Type` header - this is required
  as browsers need to append their own boundary to the header

0b9c5037f7 Deferred: Respect source maps in jQuery.Deferred.exceptionHook
So far, `jQuery.Deferred.exceptionHook` used to log error message and stack
separately. However, that breaks browser applying source maps against the stack
trace - most browsers require logging an error instance. This change makes us
do exactly that.

One drawback of the change is that in IE 11 previously stack was printed
directly and now just the error summary; to get to the actual stack
trace, three clicks are required. This seems to be a low price to pay
for having source maps work in all the other browsers, though.

Safari with the new change requires one click to get to the stack trace
which sounds manageable.

6d1364431b Ajax: Support headers for script transport even when cross-domain
The AJAX script transport has two versions: XHR + `jQuery.globalEval` or
appending a script tag (note that `jQuery.globalEval` also appends a
script tag now, but inline). The former cannot support the `headers`
option which has so far not been taken into account.

For jQuery 3.x, the main consequence was the option not being respected
for cross-domain requests. Since in 4.x we use the latter way more
often, the option was being ignored in more cases.

The transport now checks whether the `headers` option is specified and
uses the XHR way unless `scriptAttrs` are specified as well.

b02a257f98 Build: Run GitHub Action browser tests on Playwright WebKit
So far, we've been running browser tests on GitHub Actions in Chrome
and Firefox. Regular Safari is not available in GitHub Actions but
Playwright WebKit comes close to a dev version of Safari.

With this change, our GitHub CI & local test runs will invoke tests on
all actively developed browser engines on all PRs.

Also, our GitHub Actions browser tests are now running on Node.js 18.

Detection of the Playwright WebKit browser in support unit tests is done
by checking if the `test_browser` query parameter is set to `"Playwright"`;
this is a `karma-webkit-launcher` feature. Detecting that browser via
user agent as we normally do is hard as the UA on Linux is very similar
to a real Safari one but it actually uses a newer version of the engine.

In addition, we now allow to pass custom browsers when one needs it;
e.g., to run the tests in all three engines on Linux/macOS, run:
```
grunt && BROWSERS=ChromeHeadless,FirefoxHeadless,WebkitHeadless grunt karma:main
```

09d988b774 Selector: Make selector lists work with qSA again
jQuery 3.6.2 started using `CSS.supports( "selector(SELECTOR)" )` before using
`querySelectorAll` on the selector. This was to solve gh-5098 - some selectors,
like `:has()`, now had their parameters parsed in a forgiving way, meaning
that `:has(:fakepseudo)` no longer throws but just returns 0 results, breaking
that jQuery mechanism.

A recent spec change made `CSS.supports( "selector(SELECTOR)" )` always use
non-forgiving parsing, allowing us to use this API for what we've used
`try-catch` before.

To solve the issue on the spec side for older jQuery versions, `:has()`
parameters are no longer using forgiving parsing in the latest spec update
but our new mechanism is more future-proof anyway.

However, the jQuery implementation has a bug - in
`CSS.supports( "selector(SELECTOR)" )`, `SELECTOR` needs to be
a `<complex-selector>` and not a `<complex-selector-list>`. Which means that
selector lists now skip `qSA` and go to the jQuery custom traversal:
```js
CSS.supports("selector(div:valid, span)"); // false
CSS.supports("selector(div:valid)"); // true
CSS.supports("selector(span)"); // true
```

To solve this, this commit wraps the selector list passed to
`CSS.supports( "selector(:is(SELECTOR))" )` with `:is`, making it a single
selector again.
