If `union` ignores that such a rectangle has no area then maybe, but
that would be strange and unexpected, and I've certainly seen `union`
implementations of geometry libraries that do not behave like that.
Note that there is the related open issue "Issue 11: Need to define
what the union of rectangles with no area means."
