Simple (ha!) idea, it would be nice if when using the pop-out picture-in-picture mode, the captions would follow the popped out picture. Currently the captions remain on the (now empty) box where the video was previously placed.
I think - but am not sure - Firefox has a different implementation of picture-in-picture mode than Chromium, but I'm not sure - and I guess this isn't really the place to discuss that anyway
Thanks!
(note this is for desktop Firefox, though I suppose, maybe, also other versions?)
