Comment (by strk):
So it turns out the two edges of the topology (part of the outer ring of
the face which we can't build a geometry) have an interior/interior
intersection but ValidateTopology isn't able to tell.
Current ValidateTopology uses ST_Relate to tell if there's an
interior/interior intersection, but that function is unable to spot this
case as reported in #6137
