// observer which in turn releases the capture handle which can cause the
// WebContents to be reloaded on Android where we have auto-reload. This reload
// occurs *during* crash handling, leaving the frame in an invalid state and
// leading to a crash when it subsequently unloaded.
// This is fixed by deferring it to a PostTask.
