I do not agree that it is expected. There is basically no way to
distinguish between

* Heading<region beginning><folded text>
<region end>

and

* Heading<folded text><region-beginning>
<region-end>

That said, your example indeed demonstrated that my suggestion would
cause feature regression. Although, IMHO, not severe one, as
demonstrated by the above example.

It can, but does not have to. And the problem with face :extend Org
users experience usually happens when there is no extra newline.
