The current invalidation logic does not take into account the clipChildren
flag. When this flag is set to false on a container (an uncommon but
possible case), it is possible for views in the child hierarchy of
the container to be draw outside of the container's bounds. But invalidations
on that view hiearrchy can be clipped to the container's bounds, causing us to
not redraw views outside of those bounds.
Fix is to expand the dirty rect of an invalidation to encompass the complete
bounds of any container with clipChildren==false.
