-
-We don't currently have an estimate of when we will enable the `NetworkService` by
-default in Electron, but as Chromium is already removing non-`NetworkService`
-code, we will probably switch before Electron 10.
-
-The content of this document should be moved to `protocol.md` after we have
-enabled the `NetworkService` by default in Electron.
-
-> Register a custom protocol and intercept existing protocol requests.
-
-Process: [Main](../glossary.md#main-process)
-
-An example of implementing a protocol that has the same effect as the
-`file://` protocol:
-
-```javascript
-const { app, protocol } = require('electron')
-const path = require('path')
-
-app.whenReady().then(() => {
-  protocol.registerFileProtocol('atom', (request, callback) => {
-    const url = request.url.substr(7)
-    callback({ path: path.normalize(`${__dirname}/${url}`) })
-  })
-})
-```
-
-**Note:** All methods unless specified can only be used after the `ready` event
-of the `app` module gets emitted.
-
-## Using `protocol` with a custom `partition` or `session`
-
-A protocol is registered to a specific Electron [`session`](./session.md)
-object. If you don't specify a session, then your `protocol` will be applied to
-the default session that Electron uses. However, if you define a `partition` or
-`session` on your `browserWindow`'s `webPreferences`, then that window will use
-a different session and your custom protocol will not work if you just use
-`electron.protocol.XXX`.
-
-To have your custom protocol work in combination with a custom session, you need
-to register it to that session explicitly.
-
-```javascript
-const { session, app, protocol } = require('electron')
-const path = require('path')
-
-app.whenReady().then(() => {
-  const partition = 'persist:example'
-  const ses = session.fromPartition(partition)
-
-  ses.protocol.registerFileProtocol('atom', (request, callback) => {
-    const url = request.url.substr(7)
-    callback({ path: path.normalize(`${__dirname}/${url}`) })
-  })
-
-  mainWindow = new BrowserWindow({ webPreferences: { partition } })
-})
-```
-
-## Methods
-
-The `protocol` module has the following methods:
-
-### `protocol.registerSchemesAsPrivileged(customSchemes)`
-
-* `customSchemes` [CustomScheme[]](structures/custom-scheme.md)
-
-**Note:** This method can only be used before the `ready` event of the `app`
-module gets emitted and can be called only once.
-
-Registers the `scheme` as standard, secure, bypasses content security policy for
-resources, allows registering ServiceWorker and supports fetch API. Specify a
-privilege with the value of `true` to enable the capability.
-
-An example of registering a privileged scheme, that bypasses Content Security
-Policy:
-
-```javascript
-const { protocol } = require('electron')
-protocol.registerSchemesAsPrivileged([
-  { scheme: 'foo', privileges: { bypassCSP: true } }
-])
-```
-
-A standard scheme adheres to what RFC 3986 calls [generic URI
-syntax](https://tools.ietf.org/html/rfc3986#section-3). For example `http` and
-`https` are standard schemes, while `file` is not.
-
-Registering a scheme as standard allows relative and absolute resources to
-be resolved correctly when served. Otherwise the scheme will behave like the
-`file` protocol, but without the ability to resolve relative URLs.
-
-For example when you load following page with custom protocol without
-registering it as standard scheme, the image will not be loaded because
-non-standard schemes can not recognize relative URLs:
-
-```html
-<body>
-  <img src='test.png'>
-</body>
-```
-
-Registering a scheme as standard will allow access to files through the
-[FileSystem API][file-system-api]. Otherwise the renderer will throw a security
-error for the scheme.
-
-By default web storage apis (localStorage, sessionStorage, webSQL, indexedDB,
-cookies) are disabled for non standard schemes. So in general if you want to
-register a custom protocol to replace the `http` protocol, you have to register
-it as a standard scheme.
-
-### `protocol.registerFileProtocol(scheme, handler)`
-
-* `scheme` String
-* `handler` Function
-  * `request` ProtocolRequest
-  * `callback` Function
-    * `response` (String | [ProtocolResponse](structures/protocol-response.md))
-
-Registers a protocol of `scheme` that will send a file as the response. The
-`handler` will be called with `request` and `callback` where `request` is
-an incoming request for the `scheme`.
-
-To handle the `request`, the `callback` should be called with either the file's
-path or an object that has a `path` property, e.g. `callback(filePath)` or
-`callback({ path: filePath })`. The `filePath` must be an absolute path.
-
-By default the `scheme` is treated like `http:`, which is parsed differently
-from protocols that follow the "generic URI syntax" like `file:`.
-
-### `protocol.registerBufferProtocol(scheme, handler)`
-
-* `scheme` String
-* `handler` Function
-  * `request` ProtocolRequest
-  * `callback` Function
-    * `response` (Buffer | [ProtocolResponse](structures/protocol-response.md))
-
-Registers a protocol of `scheme` that will send a `Buffer` as a response.
-
-The usage is the same with `registerFileProtocol`, except that the `callback`
-should be called with either a `Buffer` object or an object that has the `data`
-property.
-
-Example:
-
-```javascript
-protocol.registerBufferProtocol('atom', (request, callback) => {
-  callback({ mimeType: 'text/html', data: Buffer.from('<h5>Response</h5>') })
-})
-```
-
-### `protocol.registerStringProtocol(scheme, handler)`
-
-* `scheme` String
-* `handler` Function
-  * `request` ProtocolRequest
-  * `callback` Function
-    * `response` (String | [ProtocolResponse](structures/protocol-response.md))
-
-Registers a protocol of `scheme` that will send a `String` as a response.
-
-The usage is the same with `registerFileProtocol`, except that the `callback`
-should be called with either a `String` or an object that has the `data`
-property.
-
-### `protocol.registerHttpProtocol(scheme, handler)`
-
-* `scheme` String
-* `handler` Function
-  * `request` ProtocolRequest
-  * `callback` Function
-    * `response` ProtocolResponse
-
-Registers a protocol of `scheme` that will send an HTTP request as a response.
-
-The usage is the same with `registerFileProtocol`, except that the `callback`
-should be called with an object that has the `url` property.
-
-### `protocol.registerStreamProtocol(scheme, handler)`

+Date: Tue, 21 Jul 2020 19:41:11 +0000
+Subject: Allow focus to move into an editable combobox's listbox
+
+In bug 593646 (https://codereview.chromium.org/2024053003/) a rule was
+added, apparently similar to a rule in WebKit, that prevents
+aria-activedescendant on an editable combobox field from moving focus
+into its listbox. However, removing this condition fixes an issue where
+the first item is not read. It also improves the verbalization,
+providing the user with the positional info, e.g. "2 of 5".
+Removing this line also does not seem to break the example attached to
+bug 593646.
