We cannot stop looking for a legacy fallback root, just because we've
found something that was marked earlier. It may be that an ancestor has
become a fragmentation context root since last time.

Add two crash tests. The first one being more true to the original
fuzzer test, while the other one is simplified (note that the DCHECK
failure happens somewhere else for this one).
