Support screenlocked video playing
On TubeLab 1.4.1 with Lineage 17.1, locking the screen leads to the video continuing to play for a couple of seconds (10-20s), then freezing. It is then impossible to restart it. It would be nice to be able to play the video entirely without the screen. If that's not possible it would be cool to have the time when the video stopped saved so that the video restarts from there and not from the beginning.
