I have been running with the fix for awhile and didn’t notice anything. No one 
seems to have complained either. (Hopefully there are people building master

I think we can apply this to emacs-29. Is there anything I should do? Do we 
just cheery-pick the commit into emac-29, or there are more elaborate 
operations required?
