Hello org-mode team,

I encountered the following error while opening an org buffer:

  Error during redisplay: (jit-lock-function 1) signaled (wrong-type-argument number-or-marker-p nil)

Here's the minimum reproducable content of the buffer:

  #+BEGIN_SRC markdown
  #+END_SRC

(that is, just an empty markdown source block).

I have markdown-mode https://jblevins.org/projects/markdown-mode/
installed.

After some debugging, I've found that the error happened in
`font-lock-fontify-keywords-region` function. It calls
`org-fontify-meta-lines-and-blocks` and got `t` as the result, but the
matching data is not set.

The following advice can fix the bug for me:

  (defun my/fix-org-fontify-meta-lines-and-blocks (res)
    (when (and res (null (match-beginning 0)))
      (set-match-data (list 0 0)))
    res)
  
  (advice-add 'org-fontify-meta-lines-and-blocks
              :filter-return
              #'my/fix-org-fontify-meta-lines-and-blocks)
