Advanced users from Main Wiki become Simple users on pages last edited by local users on a subwiki

STEPS TO REPRODUCE

1. Login as Admin
2. Set the User Type to be Advanced
3. Create a subwiki
4. Create a local user on that subwiki (e.g. UL1)
5. Create a page (SubwikiP1)
6. Login with the local user (UL1)
7. Create a page as well (SubwikiP2)
8. Login again as Admin
9. Go to the SubwikiP1
10. Go to the SubwikiP2
11. Create a terminal page from SubwikiP2

EXPECTED RESULTS

The Admin can create a terminal page from SubwikiP2 (page previously created and saved by UL1) as his user is Advanced.

ACTUAL RESULTS

When accessing the pages last edited by a local subwiki user, the Admin becomes a Simple User only on those pages.

If the page is edited then saved by Admin, the Advanced User is kept (requires a page refresh to display the Edit drop-down button).

The same issue can be reproduced when an (Advanced) non-Admin user from Main Wiki is added as a member of the subwiki (to have edit rights).

However, for local Advanced Users (admin or non-admin) the issue is not reproducing. If an Advanced local user access a page last saved by another (local) user, its Advanced User is kept.

The issue could not be reproduced on XWiki 12.3.
