Bug: Unexpected movement of cursor when commenting code blocks

[yoctocell <public@yoctocell.xyz>]

Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.  You don't know how to make a good report?  See

When I am inside a code block like this:

#+begin_src emacs-lisp
(use-package org
  :defer
  :config
  (setq blahblah t)) ; cursor on this line
#+end_src

and I hit "C-x C-;" to comment the line, the cursor automatically jumps
to the second line of the code block after the comment is made.  I would
expect the cursor to move forward one line like it usually does and this
only happens in Org-mode, not when I edit the code block in a separate
buffer with "C-c C-'".

#+begin_src emacs-lisp
(use-package org
  :defer ; cursor jumps to this line
  :config
  ;; (setq blahblah t))
#+end_src

This happens no matter how big the code block is, and it always jumps to
the second line of the code block.  I was able to reproduce this with
the "minimal-org.el" file.
