In rare cases, a region R which is itself not valid has an indirect child region
that is valid. When R becomes part of a valid region by expansion of another
region, then all children of R have to be erased from the set of valid regions.
This patch ensures that indirect children are erased in addition to direct
children.

Tobias: I added a reduced test case and adjusted the logic of the patch to
only recurse until the first child is found.
