As expected.  Please keep it this way for the moment.  If we don't find
a better solution, I'll do the revert on master.  Currently, I'd be more
interested if someone else sees the same or a similar problem.

With emacs -Q and just ‘display-buffer-alist’ customized and no
minibuffer dialogue in process?  Queer.

Indeed you would have to set it to nil.  And obviously my proposal is
not a solution anyway since someone might want to redirect focus without
any minibuffers being involved in the first place.

I'm currently struggling with focus redirection in various contexts -
for example, when redirecting focus from a parent to a child frame and
back again.  So far it's a lost battle :-(
