+

+
+        The change here is that JS event listeners don't keep a reference to a global object from

+

+        It's possible for RenderObject::container() to return an object that is higher
+        in the hierarchy than the repaintContainer that is being used to repaint an
+        object. For example, this can happen when running an accelerated opacity

+
