This input focus issue is a problem, indeed, but AFAIK it's one that's
difficult to fix.

This is clearly a bug.  Martin, could you take a look at it?  If we just
popped up this frame for *Completions*, minibuffer-hide-completions
should hide the frame.

Yet another bug.

Martin, can you explain this behavior?
