Some media players use the VisibilityState API as part of their media controls logic. This creates a problem for some PIP flows, where the PIP video might be owned by a tab the user has moved away from. Since switching from one tab to another while in PIP is a very common use case, this patch creates a quirk that adjusts the behavior of visibilityState to indicate that the document is visible if it has an active PIP window.
