[O] Bug: heading visibility cycling and org-narrow-to-subtree

[Ali Tofigh]

After narrowing to a subtree, folding the top level heading hides all
text except for the last letter in the last paragraph. An example:

----- 8< -----
* one
** two
   hello world
* three
----------

with cursor on heading "one", do M-x org-narrow-to-subtree (C-x n s),
then press tab, and you get:

----- 8< -----
* one...d
----------

with the "d" of "hello world" being visible.
