Log Message:
-----------
[EME] Crash pruning a back/forward-cached page that owns an open
MediaKeySession
https://bugs.webkit.org/show_bug.cgi?id=315849
Reviewed by Xabier Rodriguez-Calvar.
Invoking session.sessionClosed during document teardown can trigger an
assertion in a deferred promise
(JSDOMPromiseDeferred --
!activeDOMObjectsAreSuspended() ||
scriptExecutionContext()->eventLoop().isSuspended()).
By queueing it, we can ensure the task is dropped if the event loop is
stopped.
