bug#62832: 29.0.60; org-delete-indentation on region doesn't work when END is before BEGIN

[sbaugh]

1. emacs -Q
2. Insert the following in an org-mode buffer
* head
a
b
3. C-x h M-^ and note that it's now formatted as:
a
b
 * head
4. Undo, then M-> C-SPC M-< C-n M-^ and note that it's now formatted as:
* head a
b
5. Undo, then M-< C-SPC M-> M-^ and note that it's now formatted
(correctly) as:
* head a b

The 3rd and 4th steps are wrong, or at least inconsistent with how
normal delete-indentation works on a region.  In 4, I assume the issue
is that org-delete-indentation doesn't check to see if a region is
active before using its special logic.  No idea what's up with 3.

Did you report this to Org developers?  If not, why not?
