[iOS] Consider visibility endowments when determining if the application is
in the background
https://bugs.webkit.org/show_bug.cgi?id=316028
rdar://178458157
Reviewed by Jer Noble.
ApplicationStateTracker currently tracks a web view's UIWindowScene
activationState for determining
whether the web view is in the background or foreground. However, there are
cases where the window
scene is in the background but the web view is still responsible for presenting
content in another
foreground scene (e.g., via layer hosting). To cover those cases, teach
ApplicationStateTracker to
consider itself in the foreground if the application has a visibility endowment.
