So did I, with the same results.

I also see that this didn't work at least as far back as Emacs 25,
maybe never.

The function ibuffer-do-isearch was added by you, and was never
changed before.  I guess it somehow violates the protocol of
define-ibuffer-op or something?  Admittedly, that protocol is not
described too well in the doc string.

I have a question: ibuffer-do-isearch just calls
multi-isearch-buffers.  Does multi-isearch-buffers exit immediately,
or does it exit only when the multi-isearch is done?  If the former, I
guess this is why the problem happens.

I've added two people who might be able to help.
