+Subject: Fix UAF caused by vector operations during iteration
+
+MediaInspectorContextImpl::CullPlayers iterates through dead_players_
+to remove their events, but this can cause a GC event which can
+end up adding more players to the |dead_players_| vector, causing
+it to get re-allocated and it's iterators invalidated.
+
+We can fix this simply by not using an iterator, and removing elements
+from the vector before we trigger any GC operations that might cause
+other changes to the vector.
