-Subject: fix: patch out permissions checks in exclusive_access
+Subject: fix: adapt exclusive_access for electron needs
 
 This patch is necessary in order to properly enable
 navigator.keyboard.{(un)?lock}() functionality. We don't have a concept
 of PermissionManager nor of a Profile, so this would not affect usage of
 the API.
 
-We might consider potentially using our own permissions handler,
+We also need to ensure that NotifyExclusiveTabAccessLost is called
-but it's not strictly necessary for this API to work to spec.
+on all platforms in FullscreenController::ExitFullscreenModeInternal()
-
+and not just macOS, since Electron's native window impls report state
-Profile check has been upstreamed at https://chromium-review.googlesource.com/c/chromium/src/+/3247196
+change fairly instantly as well, and so pressing escape won't work on
+Linux or Windows to un-fullscreen in some circumstances without this
+change.
