Summary: Groups encountered a pretty major crash where, in many cases, we would find that DrawCommands and Views were out of sync. This turns out to be due to the fact that when we drop views from the root view, we remove each child using removeChildAt (which ultimately causes an invalidate and redraw). If this happens for a FlatViewGroup, this causes issues where the Views are all removed, but there are some DrawCommands (potentially DrawViews) that aren't removed, hence them going out of sync.
