Suppose we have the following document
```
#+title: test-file
* This is h1
** This is h1.2
We introduce some text here
Then we narrow to this heading and introduce a footnote
* Another heading here so that footnote capture works
#+begin_src
(org-element-property :buffer (org-element-at-point))
#+end_src
* Footnotes
```
When we narrow to h1.2 (subtree) so that * Footnotes is not visible - after
adding the footnote, when we check
(org-element-property :buffer (org-element-at-point)) at any headline level
or anywhere
It returns nil - inplace of the #<buffer> element it should return
This causes functions to fail that rely on this.
I am on Org mode version 9.8-pre (release_9.7.11-145-g28b631 -- the version
we get when we clone the git today (2024-10-03)
Thank you, let me know if you need any information in reproducing it.

Dear Maintainers,
I seem to have been able to solve this issue through some brute force debugging.
The problem emanates from when copying over the local variables, especially the `buffer-file-name' variable
The function definition `org-src--edit-element' contains a provision to make the said variable nil - but it is quickly reset during initialisation of the buffer just 1 line downstream. Moving the setq statement 4 lines below seems to solve the issue,
Herein I give the patch,
```

The following in .init can also be done by users not willing to patch the source file `org-src.el'
