How to reproduce:
Equip Moonwell Chalice - use it and get 1700 mastery
Unequip Moonwell Chalice - equip any other trinket (or literally just take it off) and the buff persists and cannot be disabled with right click.
How it should work:
[Hotfix] (https://worldofwarcraft.com/en-us/news/3019413/) (2011-09-08): Moonwell Chalice should no longer grant its mastery rating bonus when the activating player unequips it.
After unequipping it the buff (on-use) should disappear.
