I'm unable to reproduce this bug in Emacs 28.  The way prompts work with
asynchronous messages has changed substantially over the last year,
which probably explains it.  So I'm closing this bug report -- if
there's still an issue here, please respond to the debbugs address and
we'll reopen the bug report.
