bug#52771: 29.0.50; org-fill-paragraph does not work for several plain lists

[Rudolf Adamkovič via Bug reports for GNU Emacs, the Swiss army knife of text editors]

Reproduction steps:

1. start "emacs -Q"
2. type "C-x C-f" and "test.org" and RET
3. type the following:
   
- one
 two

- three
 four

4. mark all with "C-x h"
5. type "M-q" to fill

Actual:

- one
 two

- three four

Expected:

- one two

- three four

According to 'org-fill-paragraph' documentation:

> The REGION argument is non-nil if called interactively; in that
> case, if Transient Mark mode is enabled and the mark is active,
> fill each of the elements in the active region, instead of just
> filling the current element.

This works well for paragraphs but not for plain lists.
