      Description

      Steps to reproduce:

      1. Log in as Admin
      2. From Administration > User & Rights create a new user
      3. Add the user in a Group
      4. Click on Remove to delete the user from the group

      Expected results: The user is removed from the group.

      Actual results: Nothing happens. If the user clicks again on Remove then this appears in the wiki console:

      NOTE: This issue is present on subwikis too, also when trying to remove an user from a subwiki.

      The workaround is to refresh the page / close the group box and the user is removed.

      Working on XWiki 12.6.1!
