Bug: org-element-at-point on headline does not contain :parent property [9.3 (release_9.3 @ /home/yantar92/.emacs.d/straight/build/org/)]

[Ihor Radchenko]

Recipe:
1. Create an org file with the following contents:

* 1
** 2

2. emacs -Q
3. Open the file
4. Put the point at the end of the second headline
5. M-: (message "%s" (org-element-at-point))

Expected behaviour:

According to org-element-at-point docstring, "Properties depend on
element or object type, but always include :begin, :end, :parent and
:post-blank properties.". Hence, it is expected to have :parent property
set to the first headline.

Observed behaviour:

(headline (:raw-value 2 :begin 6 :end 13 :pre-blank 0 :contents-begin
nil :contents-end nil :level 2 :priority nil :tags nil :todo-keyword nil
:todo-type nil :post-blank 2 :footnote-section-p nil :archivedp nil
:commentedp nil :post-affiliated 6 :title 2))

No :parent property is returned.

Best,
Ihor
