Steps to reproduce:
- Navigate to Youtube.com (or other video of choice)
- Play the video, and full screen it
- Mute the video
- Change windows (so that the full-screened video is no longer on the screen)
- Go back to the video
This behaviour occurs with compatibility mode on. Safari does not have this problem. The video is not paused if unmuted and unfocused.
The video should continue to play in the background and not get paused.
