Add m3u8 file (via overlay) from first item in http://localhost:9090/@dispatch:5. It doesn't auto-invoke the player (which is fine since this is not valid video)
[ ] Add video (via overlay) from the a valid video -- the queue doesn't appear.
Add few more valid videos to the queue.
[ ] Manually invoke Play All on the queue, then refresh a few times. The entire queue is deleted.
Minor corner-case -- handle m3u8 in playlist
