* fix: prevent traffic light buttons flashing on deminiaturize
When a window with a custom `trafficLightPosition` is minimized and
restored, macOS re-layouts the title bar container during the
deminiaturize animation, causing the traffic light buttons to briefly
appear at their default position before being repositioned.
Fix this by hiding the buttons container in `windowWillMiniaturize` and
restoring them (with a redraw to the correct position) in
`windowDidDeminiaturize`.

fix: bind offscreen paint callback to child WebContents
Previously, MaybeOverrideCreateParamsForNewWindow bound the
OffScreenWebContentsView's paint callback to the parent WebContents
using base::Unretained(this). This was both unsafe (dangling pointer
risk if the parent is destroyed before the child) and semantically
incorrect — paint events belong to the child window, not the opener.
Replace the callback in MaybeOverrideCreateParamsForNewWindow with
base::DoNothing(), then rebind it to the child WebContents in
AddNewContents via a new SetCallback method on OffScreenWebContentsView.

fix: validate protocol scheme names in setAsDefaultProtocolClient
On Windows, `app.setAsDefaultProtocolClient(protocol)` directly
concatenates the protocol string into the registry key path with no
validation. A protocol name containing `\` could write to an arbitrary
subkey under `HKCU\Software\Classes\`, potentially hijacking existing
protocol handlers.
To fix this, add `Browser::IsValidProtocolScheme()` which validates that a protocol
name conforms to the RFC 3986 scheme grammar:
scheme = ALPHA *( ALPHA / DIGIT / "+" / "-" / "." )
This rejects backslashes, forward slashes, whitespace, and any other
characters not permitted in URI schemes.

* fix: use requesting frame origin instead of top-level URL for permissions
`WebContentsPermissionHelper::RequestPermission` passes
`web_contents_->GetLastCommittedURL()` as the origin to the permission
manager instead of the actual requesting frame's origin. This enables
origin confusion when granting permissions to embedded third-party iframes,
since app permission handlers see the top-level origin instead of the
iframe's. The same pattern exists in the HID, USB, and Serial device
choosers, where grants are keyed to the primary main frame's origin rather
than the requesting frame's.
Fix this by using `requesting_frame->GetLastCommittedOrigin()` in all
affected code paths, renaming `details.requestingUrl` to
`details.requestingOrigin`, and populating it with the serialized
origin only.
Co-authored-by: Shelley Vohr <shelley.vohr@gmail.com>
* chore: keep requestingUrl name in permission handler details
The previous commit changed the details.requestingUrl field to
details.requestingOrigin in permission request/check handlers. That
field was already populated from the requesting frame's RFH, so the
rename was unnecessary and would break apps that read the existing
property. Revert to requestingUrl to preserve the existing API shape.
The functional changes to use the requesting frame in
WebContentsPermissionHelper and the HID/USB/Serial choosers remain.

PowerMonitor registered OS-level callbacks (HWND UserData and
WTS/suspend notifications on Windows, shutdown handler and lock-screen
observer on macOS) but never cleaned them up in its destructor. The JS
layer also only held the native object in a closure-local variable,
allowing GC to reclaim it while those registrations still referenced
freed memory.
Retain the native PowerMonitor at module level in power-monitor.ts so
it cannot be garbage-collected. Add DestroyPlatformSpecificMonitors()
to properly tear down OS registrations on destruction: on Windows,
unregister WTS and suspend notifications, clear GWLP_USERDATA, and
destroy the HWND; on macOS, remove the emitter from the global
MacLockMonitor and reset the Browser shutdown handler.

Previously, GetProtocolLaunchPath and FormatCommandLineString in
browser_win.cc used naive quoting which could break when paths or
arguments contained backslashes, spaces, or embedded quotes.
Fix by extracting the CommandLineToArgvW-compatible quoting logic from
relauncher_win.cc into a shared utility and use it in both browser_win.cc
and relauncher_win.cc to properly quote the exe path and each argument
individually.

* fix: menu bar hiding on two setFullScreen(false)
This fixes the following bug on Linux (and maybe macOS):
1. Create a window with a menu bar.
2. Call `win.setFullScreen(false)`.
The menu bar will hide.

Previously, when trashItemAtURL: failed (e.g. on network shares or
under app translocation), the code fell back to constructing an
AppleScript that interpolated the bundle path directly into a string
literal via %@ with no escaping. This was fragile and unnecessary —
trashItemAtURL: has been the standard API since 10.8 and covers the
relevant cases. The fix simply removes the AppleScript fallback
entirely, so Trash() now returns the result of trashItemAtURL: directly.

EnterFullscreenModeForTab, RequestPointerLock, and RequestKeyboardLock
bind callbacks with base::Unretained(this); fullscreen also captures a
raw RenderFrameHost*. These callbacks may be invoked by the app's JS
permission handler after the WebContents or RenderFrameHost is destroyed.
Use GetWeakPtr() in all three call sites, and capture a
GlobalRenderFrameHostToken instead of the raw RenderFrameHost* for
fullscreen so the pointer is resolved and null-checked only when the
callback fires. Cancel in-flight permission requests from ~WebContents()
via a new ElectronPermissionManager::CancelPendingRequests()` so stale
callbacks are never handed back to JS.

Previously, UsbChooserController::OnDeviceChosen looked up the chosen
device_id via chooser_context_->GetDeviceInfo(), which searches all
known USB devices on the system rather than the filtered list shown to
the select-usb-device handler. This meant a device excluded by the
renderer's filters or exclusion_filters could still be granted
permission if the handler returned its GUID.

Inside gtk_util::GdkPixbufFromSkBitmap, g_bytes_new() was called
inline as an argument to gdk_pixbuf_new_from_bytes(), which per
GTK docs does not take ownership of the GBytes - it adds its own
internal reference. The caller's GBytes* was never stored or
unreffed, leaking 4 x width x height bytes of pixel data on every
call.

Co-authored-by: Keeley Hammond <khammond@slack-corp.com>
* refactor: use WRL ComPtr pattern for MSIX to avoid exception handling
The MSIX auto-updater code was using C++/WinRT (winrt::* namespace), which requires exception handling (/EHsc). Mixing exception and non-exception handling code in the same binary is problematic at runtime. This commit refactors electron_api_msix_updater.cc to use an upstream Chromium pattern and eliminates the need for special exception handling build flags

Starting from Chromium 134.0.6989.0 (Electron 35.0.0-beta.5), the
NativeWidgetMacNSWindow class overrides accessibilityDocument to return
the web content URL from the accessibility tree, but doesn't fall back
to NSWindow's default behavior when that URL is empty.
This broke Electron's setRepresentedFilename() API - the file path was
still set on the NSWindow, but no longer exposed via the AXDocument
accessibility attribute that screen readers use.
This fix adds an accessibilityDocument override in ElectronNSWindow that
checks representedFilename first, falling back to Chromium's behavior
for web content URLs.
