Ihor, I've given up and have upgraded to Emacs 31.1, which has Org Mode 9.8.10 built-in. I had to spend an hour fighting font lock issues (not just with Org Mode, so it's something I'm doing in my rather large, decades-old init), but have a workaround that's good enough.
Thank you for your help and your time, and thank you again for your work on Org Mode.
