When an extension background page contains a video playing in Picture-in-Picture mode, it should not be killed as video is tied to the web content. In other words, as soon as background page is killed, the Picture-in-Picture window is closed.
I think we should make prevent extension backgrond page to be killed as long a video is playing in Picture-in-Picture mode.
