Subject: [BUG] Org-cycle strange behaviour in Emacs 29.0.50 [9.5.3 (9.5.3-g0b07b3 @ /home/yaslam/.emacs.d/straight/build/org/)]

Emacs  : GNU Emacs 29.0.50 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.31, cairo version 1.16.0)
 of 2022-05-09
Package: Org mode version 9.5.3 (9.5.3-g0b07b3 @ /home/yaslam/.emacs.d/straight/build/org/)

I have strange behaviour in Emacs 29.0.50 and the org-cycle function inside org-mode, my config is normal and I haven't changed the behaviour for the TAB key inside org-mode.

When I am in an org-mode document, pressing TAB doesn't show subtrees, I bound org-cycle to double click on the mouse and it works everytime, just when pressing TAB on a heading, it doesn't show the content of that heading until I unfocus and then refocus the Emacs window.

I switched back to Emacs 27.2 and went into one of my files that are in org-mode, and org-cycle works perfectly when pressing TAB everytime.

This might be an issue not related to org-mode in Emacs 29.0.50, but pressing TAB in markdown-mode for example which also collapses heading content, it works perfectly when pressing TAB to show contents, and pressing TAB again to hide contents, but just in org-mode on Emacs 29.0.50 pressing TAB has strange behaviour, so I thought that org-cycle (the function that is called when pressing TAB by default) would be the problem, but I don't know.
