Sure.  With

--8<---------------cut here---------------start------------->8---

#+BEGIN_SRC elisp
  (require 'cl-lib)
  (message "test")
#+END_SRC
--8<---------------cut here---------------end--------------->8---

in /tmp/scratch.org, run

  emacs -Q --eval "(setq org-src-fontify-natively t)" --visit /tmp/scratch.org

Go to the code block and hit C-c ' (org-edit-special), and then exit
with another C-c '.  Without this change, the source block is no longer
highlighted as elisp code when I return to the buffer.

I don't think it's just something odd on my end because, when we
backported 6711a21, a user reported that he lost highlighting in source
blocks.
