When such a mapping is made, rather than directly map the immediate interior clusters directly we will instead invalidate their mappings to force re-evaluation (producing a "ripple effect" that will result in all deeply nested clusters being remapped).
Also improved the remapping logic so that only invalidated mappings are remapped. Previously mappings for both planes would be updated when either was invalidated. This is not an issue presently but in the future this will reduce map geometry regeneration.
