[Webkit-unassigned] [Bug 185191] document.open() event listener removal is not immediate

--- Comment #1 from Chris Dumez <cdumez at apple.com> ---
I believe the issue is that EventListenerMap::clear() clears m_entries but fails to call markAsRemoved() on each RegisteredEventListener. Therefore, if somebody already had a reference to the RegisteredEventListeners, it can still fire events at them.
