Thanks, this looks good to me.  Since this bug is a regression from
Emacs 26, it should be fixed before releasing 27.1.  Eli, is this patch
okay for emacs-27?  If no, we might also consider reverting [0e4dd67aae]
2019-10-27 "* lisp/emacs-lisp/seq.el: Don't require cl-lib." (cc'ing
Stefan, author of that patch).
