That's exactly the solution I had in mind.  I suggest that you push it
to the Emacs Git repository without waiting for the solution of the
larger issue (which will take me some time to design and test).

Btw, the reason you didn't see the problem is that the list of
candidates in your case was very small.  That's what the workaround
with ido-max-prospects <= 7 does when the list is longer.
