Definitely a known issue. No easy way to fix it without someone doing a deep pass on syntax propertization I think. I have a version of rainbow delimiters mode that tries to work around this at least for font locking, but it is severely broken and has some nasty quadratic performance issues in large files. I'll have to look into the proposed solution that Tim mentions, I may have missed it (unless it was the solution for <> that John mentions in the linked thread, in which case that one is not sufficient). Here is a discussion from back in April. https://lists.gnu.org/archive/html/emacs-orgmode/2021-04/msg00031.html
