* What I'm experiencing:
A custom ~org-num-format-function~ causes ~org-latex-preview~ warn when it
is called.

* Exact "Warning" I'm getting.
⛔ Warning (org-element-cache): org-element--cache: Org parser error in
ask.org::648. Resetting.
 The error was: (error "Invalid search bound (wrong side of point)")
 Backtrace:
nil

* Info about when this Warning comes:
- Warning comes up when equation change from "previewed-state (image)" back
to "text-state"
- Warning only comes when the equation is changed.

* Setup (the custom ~org-num-format-function~)
#+begin_src elisp
(defun my/org-num-format (numbering)
    (concat
     (number-to-string (car numbering)) "." (mapconcat (lambda (x) (format
"%02d" x)) (cdr numbering) ".") " "))

(setq org-num-format-function #'my/org-num-format)
#+end_src

#+RESULTS:
: my/org-num-format

* To Reproduce

1. Change the org-num-format-function as written above
2. (In org-file) Turn-on ~org-num-mode~
3. (In org-file) On any equation, change it.
4. run ~org-latex-preview~ to preview the equation image.
5, run ~org-latex-preview~ go back to text mode. (here warning comes)
(If warning doesn't appear try from step 3 again)
(When org-num-mode turned off, it doesn't produce warning)

Thanks for reporting!
I was able to reproduce using the provided steps using the built-in Org
mode version and using the latest stable Org mode version.
However, I am unable to reproduce using the latest development Org mode
version.
