bug#57214: 29.0.50; Incorrect rendering of Emoji (grapheme cluster) in Org heading |

Dear maintainers,
I have encountered a bug where grapheme clusters are not rendered
properly when used inside of a folded heading in Org.
Steps to reproduce with 'emacs -Q':
1. Evaluate:
(setq org-pretty-entties t
org-ellipsis " ☀️")
2. Either visit an existing Org file or use the attached sample.
3. Fold a heading in Org by pressing TAB with point somewhere on the
heading.
4. Notice the incorrectly rendered sun emoji at the end of the folded
heading.
If I change 'org-ellipsis' to a single character emoji, such as the
generic smile, the problem no longer occurs:
* Evaluate:
(setq org-ellipsis " 😀")
* Then in the Org file do 'M-x org-mode-restart'.
The smile emoji renders properly at the end of the folded heading's
line.
The attached screenshots show the different results.
All the best,
Protesilaos (or simply "Prot")
