No, not really.  What I do see is that _sometimes_, very rarely, the
number disappears from the mode line, and sometimes it's there, but
without the face.  However, mostly it is there, and with the right
face, well after the count gets beyond 10.  So the problem is more
subtle than what you seem to think.

Yes.

Maybe.  Not sure.  My question was trying to encourage you to
investigate on your own.
