[BUG] org-set-tags-command hangs indefinitely in some indirect buffers [9.7-pre (release_9.6.6-412-g2f7b35 @ /home/adam/.emacs.d/straight/repos/org/lisp/)]

[Adam Beckmeyer]

Hi everyone,

In some of my files, org-set-tags-command hangs indefinitely when invoked in an 
indirect buffer. Attached is an example file where you can see the behavior:

1. Open this file in org-mode.
2. Invoke org-tree-to-indirect-buffer in the "Hello World" heading
3. Invoke org-set-tags-command in the new indirect buffer.

I noticed this problem on git master but bisected and found the bug was 
introduced by: 
https://git.savannah.gnu.org/cgit/emacs/org-mode.git/commit/?id=2f7b35ac89470f17937f5c20524c38db103aaa4c

Emacs  : GNU Emacs 29.1 (build 2, x86_64-unknown-linux-gnu, X toolkit, cairo 
version 1.16.0)

Package: Org mode version 9.7-pre (release_9.6.6-412-g2f7b35 @
