When a user has already allowed a website to access microphone and camera,
disabling camera sharing would not fully prevent the website from
re-enabling it without an additional prompt. This was only possible if the
website kept recording with the microphone until re-enabling the camera.
This vulnerability affects Firefox < 89.
