Hi ,

I would like to report a simple bug that occurred in Org mode.

When the content of Org file is as below,


* testA
- test1
  Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod
tempor incididunt ut labore et dolore magna aliqua.


If I run org-fill-paragraph after selecting the entire line starting with
"Lorem ipsum", the result will be as follows.


* testA
- test1 Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do
eiusmod
  tempor incididunt ut labore et dolore magna aliqua.


On the other hand, if I change major-mode to text-mode in the same file and
do the same operation (fill-paragraph), the result is as follows.


* testA
- test1
  Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod
  tempor incididunt ut labore et dolore magna aliqua.


In this case, I think org-fill-paragraph should work as same as
fill-paragraph in text-mode.

Additionally, if I add line-break(\\) at the end of test1, it works fine.
However, I still think that after selecting a region, it should behave like
fill-paragraph regardless of whether there is a line break in the list
header.

My testing environment is as below.

GNU Emacs 29.4 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.42, cairo
version 1.18.0)
Org mode version 9.6.15 (release_9.6.15 @ /usr/share/emacs/29.4/lisp/org/)

Thank you.

Best regards,
Seungki Kim
