Thanks Eli for the explanation. Sorry for the trouble. It looks like
Ivy (at least, in ivy-dispatching-done) assumes the old behavior, to
wit, that echo-area messages will overwrite the minibuffer prompt,
leading to the regression discussed in
https://github.com/abo-abo/swiper/issues/2444. The conversation will
continue over there, I guess.
