Group drop downs are not refreshed correctly with new groups

Contribute Bug
1

How to reproduce

  1. Create a group
  2. Create a category
  • in the security tab, choose the new group (it should appear)
  • in the settings tab, choose the new group as moderator (it should not appear)
  1. Reload the page
  • the new group should appear in both cases

I guess this is related to that one: Newly-created groups don't show up in category permissions without refresh
