When playing html5 video in picture in picture mode it will remember its last position where it played last time Is there a way to force the picture in picture window to appear at some specific position? CSS pseudo-class ":picture-in-picture" does not have any effect , is this working? found only this example https://developer.mozilla.org/en-US/docs/Web/CSS/:picture-in-picture and it is not very clear with todo with it. My Idea tells that ":picture-in-picture" is "Unknown pseudo selector"
