[BUG] org-highlight-latex-and-related naive + script renders links improperly

Hello,

I have encountered following bug when I set =native= and =script= in 
=org-highlight-latex-and-related=:
Expected behaviour: Links are displayed as before.
Actual behaviour: If a link contains an underscore (which is quite
common), then a "subscript" is displayed as part of the link.

Example: The link

[[https://en.wikipedia.org/wiki/Harmonic_series_(mathematics)][Text]]

is rendered as

_seriesLinkb

with a small "s", and "_series" and "Text" fontified differently, but 
all of it is still recognized as the link (e.g., highlighted and 
clickable on mouseover).

Tested on Debian Testing with emacs -Q where:
Emacs  : GNU Emacs 29.1 (build 1, x86_64-pc-linux-gnu, GTK+ Version 
3.24.38, cairo version 1.16.0)
  of 2023-08-30, modified by Debian
Package: Org mode version 9.6.6 (release_9.6.6 @ 
/usr/share/emacs/29.1/lisp/org/)

Additional info:
The bug does not seem to occur when =latex= and =script= is used (but 
=native= looks better, so I would like to keep it).
Considering the much improved readability 
=org-highlight-latex-and-related= gives for documents with latex mixed 
in, the malformed link rendering is not a major problem, but confusing 
nonetheless. So it would be nice if this could be fixed.

Thank you and best,
Michael

Confirmed.
Yet another bug caused by approximate fontification based on regexps
rather than on Org parser.
