The only time that the ancestor spatial node index is read is
during push_stacking_context. This means that even if it was
used as an ancestor for a 3d context, we can safely collapse
it in to the parent stacking context during flattening, if it
is otherwise redundant.
This is a partial fix for picture caching heuristics failing
with the display list produced on mobile devices.
