Re: org-element-cache error when storing footnotes using capture buffer

[Akash <akashpaul21@gmail.com>]

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'
