On mediawiki.org page, unregistered users can't edit LQT posts. It doesn't matter if the message was originally posted by the same user or not.
When editing a post, the edit form is displayed as normal. But when saving the edit, the "progress" icon appears and nothing more happens.
Inspecting what's going on in the AJAX calls, I can see the edit request is posted, but the server response is:
{"servedby":"mw1202","error":{"code":"editconflict","info":"Edit conflict detected"}}
If I edit the post as a logged in user, the same info is sent to the API when saving the edit, except the "token" which is different, so I can't see how it's detecting edit conflicts.
I'm going to open another bug requesting a better handling of those error responses from the server, since the "Edit conflict detected" message isn't displayed anywhere.
