Picture-in-picture keyboard shortcuts navigation

There is no navigation keyboard shortcuts in picture-in-picture mode at the moment. Only Firefox supports, but I find it extremely useful.

  1. Picture-in-picture is meant to be a side thing, so if you hear something that triggers you, you frequently have an urge to rewind, and you have to go back to the source tab to do - extra few seconds it’d be cool to spare.
  2. Also, since PIP typically does not show a progress bar, it adds a level of excitement of not knowing when the video would be over for sports (especially EA sports) events. Going to the source tab to rewind spoils that as well.

Expected result:
Back and forward arrows work to rewind video in PIP mode. Preferably shift-back and shift-forward work as well.
