Subject: bug#53758: 28.0.91; Recursive edit during dired-do-find-regexp-and-replace breaks isearch
Date: Thu, 03 Feb 2022 19:11:11 +0000 (UTC)

isearch-forward (C-s) while in a recursive edit (C-r) triggered from
dired-do-find-regexp-and-replace (Q in a dired buffer) always fails to
find any matches for any string, even if there are matches in the
buffer.

Steps to reproduce:
1. Open a dired buffer in a directory containing at least one file which
contains some text (e.g. "Hello world")
2. Run dired-do-find-regexp-and-replace to replace "Hello" with
"Goodbye" ("Q Hello RET Goodbye RET"); this will switch buffers
to the first matching file.   
3. Type C-r to enter a recursive edit (I'm guessing this runs
(recursive-edit)?)
4. At the start of the buffer, run isearch-forward searching for "world"
("C-s world RET")
5. Note that the isearch fails despite "world" being in the buffer.

For what it's worth, this interestingly doesn't happen with
project-query-regexp-replace (which also does multi-file query-replace).
