In org mode, evaluate the expression and narrow the buffer to the first
C-x n s).
* one (setq org-refile-targets '((nil . (:maxlevel . 3)))) ** two ** three * four
Now put point on the second heading and refile it to the third (
C-w). It will disappear and only appear again after the buffer has
been widened (
C-x n w). Is this a bug?
