[DUPLICATE] [Warlock] Healthstone

[Insanelock]

WoW Freakz spell link: http://www.wowhead.com/item=5512/healthstone
Bug description: The healthstone is supposed to have one minute cooldown, however I encountered a problem in arenas where I used the healthstone at the arena beggining, and couldn't use it after the cooldown ended. The healthstone wasn't on CD, I still had two charges, but I couldn't use it.
Proof:
First use of healthstone during duel:


And after the CD is done, I'm trying to use it but to no avail:

You can use 1 healthstone per combat, in both pics, you were in combat. Rejected.

This was already reported. It is because healthstone will only start its cooldown once you come out of combat (or you leave arena, etc)...
