FWIW, I reported this problem long, long ago. I don't recall the bug # (it might
have been before we had bug #s), and I can't seem to locate the bug report now.
This problem is at least as old as Emacs 20. It can be very distracting.
BTW, I notice this happening especially when debugging a command invoked (via a
key) from the minibuffer. But your recipe is a good one at top level.
