YouTube playlists do seem to work. Can you think of another playlist that might fail? I do want to file a bug, but I would like to have an example.

I think I might…still thinking this over actually. I can imagine kind of see it either way. If the video is still playing and the audio is still happening, it seems like it shouldn't matter that it has been scroll offscreen? But if the video stopped because it was scrolled away, then then we do care. We'll have to think this through.

Thank you!
