Can't change categories order through drag and drop in admin with permission "Community"
I think I found an issue, or maybe I did a mistake in the configuration but I have a problem (or maybe that's not possible to do) but I've a problem :
I gave to moderator group the "community" permission, that allows to manage Categories in the back office. Then I logged in with a moderator account, I am able to create categories and save them, but not to move them with the drag and drop feature. I mean the drag and drop works well, but after saving and refreshing the page, the order defined isn't saved...
Any help would be appreciated, thanks !
Vanilla 2.2 (don't know the exact version because I'm not at home, but it was downloaded about 2 weeks ago).
