[BUG] org-element-at-point: Throw an error when not in org-mode [9.7-pre (release_9.6.15-1033-gd8586f @ /home/marie/.emacs.d/straight/build/org/)]

Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.  You don't know how to make a good report?  See

I suspect that this has already been reported as I saw it here: 
https://www.mail-archive.com/emacs-elpa-diffs@gnu.org/msg102743.html.

Just wanted to make sure it got to the right channel. Apologies for a useless 
message if it already did.

Noticed this problem with org 9.7. Used to be no problem with prior version.

Also mentioned in 
https://www.reddit.com/r/emacs/comments/18gkx0i/orgelementatpoint_cannot_be_used_in_nonorg_buffer/.

In my case, I get the error when using `org-meta-return` in non-org buffers.

I then get either of these error messages:

Warning (org-element): ‘org-element-at-point’ cannot be used in non-Org buffer
Warning (org-element): org-element--cache: Org parser error in <my-file>. 
Resetting.

Thank you.
