Unfortunately, the solution Elvis provided does not work for me. Instead, I get the following error:
TypeError: Property 'push' of object [object Object] is not a function Of course, that means the blue rectangle stays on the screen, but only because the code after the error never gets executed (i.e. oldParent never gets destroyed). Nevertheless, I believe this would be the right track, if it is possible at all.
