Sorry, I managed to confuse myself before. Emacs-25 has Org 8.2.10, but
this bug only lives in the core version.
Isn’t a better fix to change the signature of the alias to mirror that of
font-lock-ensure? I.e.
(defalias 'org-font-lock-ensure
(if (fboundp 'org-font-lock-ensure)
#'font-lock-ensure
(lambda (&optional _beg _end) (font-lock-fontify-buffer))))
Since (org-font-lock-ensure) is called from many places.
Note, this change only lives it the Emacs version of Org. It was added in
this commit:
