Thanks for your help. The only thing that would be helpful for now is
if you could run with this patch applied for a while and look out for
anything unexpected. I don’t think it will cause problems, but you
never know!

Unfortunately, I think this will have to wait until Emacs 26.2.

Eli, should it be added to master then cherry‐picked back to emacs-26
when we’re ready, or am I best just waiting?
