[BUG] Incorrect timestamp face in a heading if previous body contains link to such a heading [9.5.2 (release_9.5.2-25-gaf6f12 @ /usr/share/emacs/28.1/lisp/org/)]

[BUG] Incorrect timestamp face in a heading if previous body contains link to such a heading [9.5.2 (release_9.5.2-25-gaf6f12 @ /usr/share/emacs/28.1/lisp/org/)]

[Hanspeter Gisler]

OBSERVED BEHAVIOR
=================

The following 2 files 'correct_face_rendering.org' and
'incorrect_face_rendering.org' render the 3rd headings timestamp face
differently, once correctly and once incorrectly.

correct_face_rendering.org
--------------------------

* ~ [2022-04-11 Mo] teading 1 - referred to by some other heading's body
:PROPERTIES:
:ID:       41482d18-460a-4803-81dc-f4512b771151
:END:
* ~ [2022-04-11 Mo] Heading 2 - referring to Heading 1
Link to: [[id:41482d18-460a-4803-81dc-f4512b771151][~ [2022-04-11 Mo] Heading 1 - referred to by some other heading's body]]
* ~ [2022-04-11 Mo] Heading 3's timestamp face is correct


incorrect_face_rendering.org
----------------------------

* [2022-04-11 Mo] Heading 1 - referred to by some other heading's body
:PROPERTIES:
:ID:       9549d52f-439d-4011-ad72-9a9a7baad58b
:END:
* [2022-04-11 Mo] Heading 2 - referring to Heading 1
Link to: [[id:9549d52f-439d-4011-ad72-9a9a7baad58b][[2022-04-11 Mo] Heading 1 - referred to by some other heading's body]] 
* [2022-04-11 Mo] Heading 3's timestamp face is incorrect


EXPECTED BEHAVIOR
=================

With both files, org should render the headings timestamp face correctly.

Confirmed.

This is yet another example (among many before) where our current
fontification engine is failing.

See https://orgmode.org/list/87ee7c9quk.fsf@localhost

The fix is WIP. Current version is at
https://github.com/yantar92/org/tree/feature/org-font-lock-element

Your example is fontified correctly in the WIP version :)

Best,
Ihor
