STEPS TO REPRODUCE
- Observe the 'Tags:' at the bottom of the pages content
- Observe again the 'Tags:'
When the user is logged out, the [+] link/symbol is not displayed. After the user logs in, the [+] is displayed.
The [+] link/symbol needs page hard refresh (CTRL + F5) to be displayed after the user is logged in.
When the user logs out, it's still displayed unless the page is hard refreshed again.
The issue could not be reproduced on XWiki 12.5.1.
