Quickly creating and destroying complex LayoutContainers can result in console errors

[NIKENIT]

Current Behavior

Sometimes, quickly creating and destroying LayoutContainers with "overflow: hidden" or "overflow: scroll" can result in console errors. I was not able to reproduce it consistently, but I crashes while trying to redraw the trackpad mask for an already destroyed container. It happends because the recalculation of the mask happends 1ms after the background has already been drawn, and does not check if the container is stil alive at that point.

Possible Solution

Check if the container is destroyed and do not attempt to recalculate the mask if it is.

Similar thing happends in _upateSize callback, if the throttle time is not 0 and the container has already been destroyed. There is no check that the element is still alive, so the update method crashes while trying to access style properties "width" and "height".
