I tried this here with emacs 25:

  (man "X")
  (y-or-n-p "-->"))

This stills behave as described: the prompt disappears and doesn't come
back from alone.

OTOH, a simple call to message done from within a timer doesn't behave
like this.  So this seems to be special to process sentinels, thus it's
probably a rare situation that this happens - a bit annoying
