isearch replace on org-mode buffer overlays caused error

I do [M-%] which bind to package "pcre2el" command
`pcre-query-replace-regexp` which replace regexp Org-mode tag ":audio:"
with text ":file_audio:" in an Org-mode buffer. The tag is beautified
with package "org-tag-beautify" https://repo.or.cz/org-tag-beautify.git.

I got error when doing [M-%] which is a keybinding remapped to package
"pcre2el" command `pcre-query-replace-regexp`.

I saw #<overlay in no buffer> in the backtrace. Don't know why.

Should the `isearch-open-necessary-overlays` exclude filter those
#<overlay in no buffer>?

That doesn't normally happen.  Isearch will only consider live overlays
living in the current buffer.

But why is this magit-mode function called in your case?
`isearch-clean-overlays@magit-mode' tries to unfold sections in a
magit-mode buffer.  I don't think it should be called in an org-mode
buffer at all.  Something's wrong here.
