> No hurry in reviewing the patch, but since this is a wrong-code bug, I suppose it should be back-ported to emacs-26. Does that mean that it should be written for that branch and then merged to master, or the other way around?

The former.

However, in this case I really wonder why we should be so eager to
install the change on the emacs-26 branch.  How long this wrong code
has been with us?
