bug#66790: 29.1; ispell breaks org-mode headings folding/unfolding

[Kai Jenkins]

recipe to create bug:
- starting emacs (via. emacs -Q)
- open a new org file
- create a heading (eg. * test)
- write some text under the heading that contains a spelling mistake
- fold the heading with tab
- run M-x ispell

the bug:
- ispell doesnt unfold the header that has the bug (possible corrections
are shown so it is finding the incorrect word)
- when you exit ispell with C-g the heading is now stuck and will not unfold 
with tab
- in the buffer theres a message "SUBTREE (NO CHILDREN)"
