Summary:
Currently the fall apart effect doesn't work in conjuction with window
open/close animation effects, e.g. scale. The reason for that is those
effects grab windows before the fall apart effect.

Test Plan:
* Enable the fall apart effect and the scale effect;
* Close a window.
(without this patch the window doesn't fall apart)
