SUMMARY
If I try to go to the previous video in a Youtube playlist, it does not work.

STEPS TO REPRODUCE
1. Open a Youtube playlist.
2. Press the previous track (⏮️) button either through the system tray icon or when the screen is locked.

OBSERVED RESULT
When opening the system tray icon, the media player shows that the video went back to the beginning (the video keeps playing as if nothing happened) and it stays in the same video after several clicks.

EXPECTED RESULT
After one click, the video should play from the beginning. After two consecutive clicks, the playlist should play the previous video.
