There's indeed little doubt that this is "as designed", it's probably
just inherited from the view of char-properties as a minor variant of
text-properties.
The result makes some sense but AFAIK in all the cases I bumped into it
it seemed like a bug rather than a feature.
So I think it's OK to consider this case as "unsupported", so any
behavior is acceptable.  Maybe the best would be to detect the situation
and signal some kind of warning.
