Changing the priority to p2 as the bug is tracked by a release manager for the current nightly.

Speaking with astevenson, we think the simplest solution is probably the best for now - we'll close the PiP player window iff the <video> being displayed is ever removed from the DOM. That will happen in bug 1583882.
