In that case info about the popup could be given whenever you execute
C-u C-x = in that buffer.  I agree with you that such behavior would
be annoying, but it could be done.  That is you could keep the rule
that C-u C-x = gives info about the current face and any popups that
are triggered.

I agree with you but would say "(very) unimportant issue"

Agreed.  I should point out that I mentioned the specific interface in
reply to Eli who asked for it.
