refactor: remove dead named-window lookup from guest-window-manager (#50498)

The frameNamesToWindow map was a holdover from the BrowserWindowProxy
IPC shim. Since nativeWindowOpen became the only code path, Blink's
FrameTree::FindOrCreateFrameForNavigation resolves named window targets
directly in the renderer, scoped to the opener's browsing context
group. When a matching named window exists, Blink navigates it without
ever sending a CreateNewWindow IPC to the browser, so this map was
never consulted in the legitimate same-opener case.

The only time the map found a match was when two unrelated renderers
happened to use the same target name, in which case openGuestWindow
would short-circuit before consuming the guest WebContents that
Chromium had already created for the new window, leaking it.

Adds a test verifying Blink handles same-opener named-target reuse
end-to-end without any browser-side tracking.

+# Copilot Instructions for Electron
+
+## Build System
+
+Electron uses `@electron/build-tools` (`e` CLI). Install with `npm i -g @electron/build-tools`.
+
+```bash
+e sync              # Fetch sources and apply patches
+e build             # Build Electron (GN + Ninja)
+e build -k 999      # Build, continuing through errors
+e start             # Run built Electron
+e start --version   # Verify Electron launches
+e test              # Run full test suite
+e debug             # Run in debugger (lldb on macOS, gdb on Linux)
+```
+
+### Linting
+
+```bash
+npm run lint              # Run all linters (JS, C++, Python, GN, docs)
+npm run lint:js           # JavaScript/TypeScript only
+npm run lint:clang-format # C++ formatting only
+npm run lint:cpp          # C++ linting only
+npm run lint:docs         # Documentation only
+```
+
+### Running a Single Test
+
+```bash
+npm run test -- -g "pattern"   # Run tests matching a regex pattern
+# Example: npm run test -- -g "ipc"
+```
+
+### Running a Single Node.js Test
+
+```bash
+node script/node-spec-runner.js parallel/test-crypto-keygen
+```
+
+## Architecture
+
+Electron embeds Chromium (rendering) and Node.js (backend) to enable desktop apps with web technologies. The parent directory (`../`) is the Chromium source tree.
+
+### Process Model
+
+Electron has two primary process types, mirroring Chromium:
+
+- **Main process** (`shell/browser/` + `lib/browser/`): Controls app lifecycle, creates windows, system APIs
+- **Renderer process** (`shell/renderer/` + `lib/renderer/`): Runs web content in BrowserWindows
+
+### Native ↔ JavaScript Bridge
+
+Each API is implemented as a C++/JS pair:
+
+- C++ side: `shell/browser/api/electron_api_{name}.cc/.h` — uses `gin::Wrappable` and `ObjectTemplateBuilder`
+- JS side: `lib/browser/api/{name}.ts` — exports the module, registered in `lib/browser/api/module-list.ts`
+- Binding: `NODE_LINKED_BINDING_CONTEXT_AWARE(electron_browser_{name}, Initialize)` in C++ and registered in `shell/common/node_bindings.cc`
+- Type declaration: `typings/internal-ambient.d.ts` maps `process._linkedBinding('electron_browser_{name}')`
+
+### Patches System
+
+Electron patches upstream dependencies (Chromium, Node.js, V8, etc.) rather than forking them. Patches live in `patches/` organized by target, with `patches/config.json` mapping directories to repos.
+
+```text
+patches/{target}/*.patch  →  [e sync]   →  target repo commits
+                          ←  [e patches] ←
+```
+
+Key rules:
+
+- Fix existing patches rather than creating new ones
+- Preserve original authorship in TODO comments — never change `TODO(name)` assignees
+- Each patch commit message must explain why the patch exists
+- After modifying patches, run `e patches {target}` to export
+
+When working on the `roller/chromium/main` branch for Chromium upgrades, use `e sync --3` for 3-way merge conflict resolution.
+
+## Conventions
+
+### File Naming
+
+- JS/TS files: kebab-case (`file-name.ts`)
+- C++ files: snake_case with `electron_api_` prefix (`electron_api_safe_storage.cc`)
+- Test files: `api-{module-name}-spec.ts` in `spec/`
+- Source file lists are maintained in `filenames.gni` (with platform-specific sections)
+
+### JavaScript/TypeScript
+
+- Semicolons required (`"semi": ["error", "always"]`)
+- `const` and `let` only (no `var`)
+- Arrow functions preferred
+- Import order enforced: `@electron/internal` → `@electron` → `electron` → external → builtin → relative
+- API naming: `PascalCase` for classes (`BrowserWindow`), `camelCase` for module APIs (`globalShortcut`)
+- Prefer getters/setters over jQuery-style `.text([text])` patterns
+
+### C++
+
+- Follows Chromium coding style, enforced by `clang-format` and `clang-tidy`
+- Uses Chromium abstractions (`base::`, `content::`, etc.)
+- Header guards: `#ifndef ELECTRON_SHELL_BROWSER_API_ELECTRON_API_{NAME}_H_`
+- Platform-specific files: `_mac.mm`, `_win.cc`, `_linux.cc`
+
+### Testing
+
+- Framework: Mocha + Chai + Sinon
+- Test helpers in `spec/lib/` (e.g., `spec-helpers.ts`, `window-helpers.ts`)
+- Use `defer()` from spec-helpers for cleanup, `closeAllWindows()` for window teardown
+- Tests import from `electron/main` or `electron/renderer`
+
+### Documentation
+
+- API docs in `docs/api/` as Markdown, parsed by `@electron/docs-parser` to generate `electron.d.ts`
+- API history tracked via YAML blocks in HTML comments within doc files
+- Docs must pass `npm run lint:docs`
+
+### Build Configuration
+
+- `BUILD.gn`: Main GN build config
+- `buildflags/buildflags.gni`: Feature flags (PDF viewer, extensions, spellchecker)
+- `build/args/`: Build argument profiles (`testing.gn`, `release.gn`, `all.gn`)
+- `DEPS`: Dependency versions and checkout paths
+- `chromium_src/`: Chromium source file overrides (compiled instead of originals)

 `desktopCapturer.getSources(options)` only returns a single source on Linux when using Pipewire.
 
 PipeWire supports a single capture for both screens and windows. If you request the window and screen type, the selected source will be returned as a window capture.
 
-`navigator.mediaDevices.getUserMedia` does not work on macOS for audio capture due to a fundamental limitation whereby apps that want to access the system's audio require a [signed kernel extension](https://developer.apple.com/library/archive/documentation/Security/Conceptual/System_Integrity_Protection_Guide/KernelExtensions/KernelExtensions.html). Chromium, and by extension Electron, does not provide this.
+### macOS versions 14.2 or higher
 
-It is possible to circumvent this limitation by capturing system audio with another macOS app like Soundflower and passing it through a virtual audio input device. This virtual device can then be queried with `navigator.mediaDevices.getUserMedia`.
+`NSAudioCaptureUsageDescription` Info.plist key must be added in order for audio to be captured by
+`desktopCapturer`. If instead you are running Electron from another program like a terminal or IDE
+then that parent program must contain the Info.plist key.
+
+This is in order to facillitate use of Apple's new [CoreAudio Tap API](https://developer.apple.com/documentation/CoreAudio/capturing-system-audio-with-core-audio-taps#Configure-the-sample-code-project) by Chromium.
+
+> [!WARNING]
+> Failure of `desktopCapturer` to start an audio stream due to `NSAudioCaptureUsageDescription`
+> permission not present will still create a dead audio stream however no warnings or errors are
+> displayed.
+
+As of Electron `v39.0.0-beta.4`, Chromium [made Apple's new `CoreAudio Tap API` the default](https://source.chromium.org/chromium/chromium/src/+/ad17e8f8b93d5f34891b06085d373a668918255e)
+for desktop audio capture. There is no fallback to the older `Screen & System Audio Recording`
+permissions system even if [CoreAudio Tap API](https://developer.apple.com/documentation/CoreAudio/capturing-system-audio-with-core-audio-taps) stream creation fails.
+
+If you need to continue using `Screen & System Audio Recording` permissions for `desktopCapturer`
+on macOS versions 14.2 and later, you can apply a Chromium feature flag to force use of that older
+permissions system:
+
+```js
+// main.js (right beneath your require/import statments)
+app.commandLine.appendSwitch('disable-features', 'MacCatapLoopbackAudioForScreenShare')
+```
+
+### macOS versions 12.7.6 or lower
+
+`navigator.mediaDevices.getUserMedia` does not work on macOS versions 12.7.6 and prior for audio
+capture due to a fundamental limitation whereby apps that want to access the system's audio require
+a [signed kernel extension](https://developer.apple.com/library/archive/documentation/Security/Conceptual/System_Integrity_Protection_Guide/KernelExtensions/KernelExtensions.html).
+Chromium, and by extension Electron, does not provide this. Only in macOS 13 and onwards does Apple
+provide APIs to capture desktop audio without the need for a signed kernel extension.

+Per [Chromium update](https://source.chromium.org/chromium/chromium/src/+/ad17e8f8b93d5f34891b06085d373a668918255e) which enables Apple's newer [CoreAudio Tap API](https://developer.apple.com/documentation/CoreAudio/capturing-system-audio-with-core-audio-taps#Configure-the-sample-code-project) by default, you now must have `NSAudioCaptureUsageDescription` defined in your `Info.plist` to use `desktopCapturer`.

 This tutorial will be most useful to those who already have some familiarity with native C++ GUI development on Windows. You should have experience with basic window classes and procedures, like `WNDCLASSEXW` and `WindowProc` functions. You should also be familiar with the Windows message loop, which is the heart of any native application - our code will be using `GetMessage`, `TranslateMessage`, and `DispatchMessage` to handle messages. Lastly, we'll be using (but not explaining) standard Win32 controls like `WC_EDITW` or `WC_BUTTONW`.

+From: Anders Hartvoll Ruud <andruud@chromium.org>
+Date: Wed, 25 Feb 2026 03:25:14 -0800
+Subject: Stringify CSSUnparsedValues via toString, as normal
+
+CSSUnparsedValue exposes a special stringification function
+ToUnparsedString() in addition to the regular toString().
+The documentation says it returns "tokens without substituting
+variables", but it's not clear what this means; we don't substitute
+any variables in CSSStyleValue::toString() either.
+
+This CL makes ToUnparsedString() private (and renames it).
+Clients needing to serialize a CSSUnparsedValue can do so via
+the normal toString() function. (If ToUnparsedString() existed
+for performance reasons, that should have been documented.)
+
+Also, the /**/-"fixup" pass over the value has been folded into
+ToStringInternal(). This is to make it easy to find the canonical string
+representation of this value within CSSUnparsedValue (without going
+through a CSSValue).
+
+The main point of this CL is to prepare for validating
+the "argument grammar" of the value during the StyleValue-to-CSSValue
+conversion in StylePropertyMap (which requires item (2) above).
+
+We now jump through additional hoops to ultimately get a string
+from the outside of CSSUnparsedValue, but there should otherwise
+be no behavior change.

+Subject: [M146][base] Fix UAF in base::OnceCallbackList on re-entrant Notify()
+
+Before this patch, `base::OnceCallbackList` was susceptible to a
+heap-use-after-free when `Notify()` was called re-entrantly.
+
+The UAF occurred because `OnceCallbackList::RunCallback()` immediately
+spliced executed nodes out of `callbacks_` and into `null_callbacks_`.
+If a nested `Notify()` executed a node that an outer `Notify()` loop was
+already holding an iterator to, and that node's subscription was
+subsequently destroyed during the re-entrant cycle, the node would be
+physically erased from `null_callbacks_`. When control returned to the
+outer loop, it would attempt to evaluate the now-dangling iterator.
+
+This CL fixes the bug by deferring list mutations until the outermost
+iteration completes:
+1. `RunCallback()` no longer splices nodes during iteration.
+2. Cancellation logic is pushed down to the subclasses via a new
+   `CancelCallback()` hook, which is an extension to the pre-existing
+   `CancelNullCallback()` with increased responsibilities and clearer
+   semantics.
+3. If a subscription is destroyed while `is_iterating` is true,
+   `OnceCallbackList` resets the node and stashes its iterator in
+   `pending_erasures_`.
+4. A new `CleanUpNullCallbacksPostIteration()` phase runs at the end
+   of the outermost `Notify()`, which safely splices executed nodes
+   into `null_callbacks_` and physically erases the pending dead nodes.
+
+As a side effect, the type-trait hack in `Notify()` based on
+`is_instantiation<CallbackType, OnceCallback>` can be removed, because
+this information is exposed directly by
+`OnceCallbackList::CleanUpNullCallbacksPostIteration()`.
+
+The newly-added unit-test
+CallbackListTest.OnceCallbackListCancelDuringReentrantNotify reproduces
+the scenario and crashed before this patch.
+

+Subject: Describe a vector of segments as "segments", not "tokens"
+
+The specification uses the term "tokens" to refer to a sequence
+of V8CSSUnparsedSegment objects, and CSSUnparsedValue has adopted
+this terminology. While it is usually a good idea for Blink
+to mirror the language used in specifications, "tokens" is very
+confusing here, since it always means CSSParserTokens in every other
+place in the style code.

+Subject: [M146] Increment WebGL context generation number on context restore
+
+Objects created while the context is lost should not be valid to use
+after the context is restored.
+- Replace number_of_context_losses_ with a "context generation number"
+  which increments on both context loss and context restore.
+  - Technically, it would make sense to increment it only on context
+    restore, but just in case any logic is relying on the current
+    behavior, increment it in both places.
+  - It's uint64_t just in case someone figures out how to increment it 4
+    billion times.
+- Remove unused WebGLRenderingContextBase::number_of_context_losses_,
+  left over from before it was moved into WebGLContextObjectSupport.
+
+(cherry picked from commit c1433740f3ea902fd6b15d63c4865ad60a3761f9)

+Subject: Validate CSSUnparsedValues upon assignment
+
+CSS Typed OM has a concept of a value "matching a grammar" (or not)
+upon assignment to a property [1]. For CSSUnparsedValues, we currently
+don't perform any significant validation, and as a consequence
+we allow "invalid" CSSUnparsedDeclarationValues to be created
+(causing DCHECKs later in the pipeline).
+
+This CL makes sure values can be parsed using CSSVariableParser::
+ConsumeUnparsedDeclaration before assignment.
+
+We're still not handling the value in the context of the destination
+property, which we probably should. This is also a problem with
+current state of things, however, so for now the goal is primarily
+to avoid the DCHECKs in Issue 484751092.
+
+Finally, I opened an issue against the specification [2], which
+currently doesn't define any of this.

+Subject: Avoid stale iteration in CSSFontFeatureValuesMap
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+To avoid invalid iterator state, take a snapshot of the
+map when creating the iteration source. This addresses
+the immediate problem of iterating while modifying.
+
+Remaining work tracked in https://crbug.com/483936078

+Subject: feat: plumb node_integration_in_worker through WorkerSettings
+
+Copy the node_integration_in_worker flag from the initiating frame's
+WebPreferences into WorkerSettings at dedicated worker creation time,
+so the value is readable per-worker on the worker thread rather than
+relying on a process-wide command line switch. The value is also
+propagated to nested workers via WorkerSettings::Copy.

+Subject: Ozone/Wayland: Treat DND drop performed with NONE action as a
+ cancellation
+
+According to the Wayland protocol, a "drop performed" event can be
+followed with a `cancelled` event. This is the behavior of compositors
+like KWin.
+
+We were always treating "drop performed" as a completed drop. This
+change corrects the logic to pass `DragResult::kCancelled` in this
+scenario.
