Reading type-break.el raised some questions: please confirm does the same
problem occur after using the default value of 'type-break-query-function'
that is 'yes-or-no-p', and not 'y-or-n-p'?

It looks like type-break uses 'run-at-time' and then tries to
call 'y-or-n-p' in the middle of an isearch.  I tried both

  (run-with-timer 5 5 #'yes-or-no-p "OK? ")
  (run-with-timer 5 5 #'y-or-n-p "OK? ")

and activated isearch.  Then the typed answer was added
to the search string.  Emacs 28 has an option
'y-or-n-p-use-read-key' that you can set for type-break
that pops up the query at random times.  But the problem
still exists for 'yes-or-no-p'.
