Sébastien reporting this upstream as bug#72254. The bug has been fixed and will become available in Emacs 30 release. The bug fix involved modifying Emacs C code, so we cannot do anything more to work around the problem on Org side. Fixed. -- Ihor Radchenko // yantar92, Org mode contributor, Learn more about Org mode at <https://orgmode.org/>.
