Re: Bug: org-cycle stops working on Org files with empty lines at end of buffer [9.4 (9.4-elpaplus @ /home/brentg/.emacs.d/elpa/org-plus-contrib-20200914/)]

Additional observation:
The unfolding does not happen because org-cycle-show-empty-lines
_always_ reveals trailing empty lines at the end of buffer. It breaks
the assumption in org-cycle-internal-local that end of folded subtree
must always be the same as the end of the folded region.

Before ee3c3b554, that situation was handled by additional check, but it
is not the case anymore.

Best,
Ihor
