Current behaviour: At the moment, after proccing Clearcasting and using Hurricane to benefit from the proc, you get the correct behaviour but the Clearcasting proc/buff icon remains, though it is already used. This causes the problem, that it is unnecessary hard to track the Clearcasting proc, as it might have already been used but the buff icon is still shown and as such it also messes up all proc tracking addons.
Expected behaviour: Clearcasting proc/buff icon should disappear when starting the cast/channeling of Hurricane, not after. Hurricane should use the Clearcasting proc when the channeling begins (you do get the no mana benefit, but the proc/buff icon remains), but also the buff icon needs to be removed when channeling begins, not after it. It is not purely visual issue, because the client seems to think you still have the proc active even after using it (on Hurricane, other spells seem to work fine).
Steps to reproduce the problem:
Make a druid, get Omen of Clarity talent from resto tree (tier 3).
Get Clearcasting proc (I just cast Hurricane on Training Dummies).
After getting Clearcasting proc, stop and cast Hurricane (again). Don't target anything with it to avoid additional Clearcasting procs. Now Hurricane costs no mana, as it should, but the Clearcasting proc is not removed before channeling ends (10 sec channeling).
Cast Hurricane once again, while channeling the previous one. You still have the Clearcasting proc/buff showing up, but you did already use the proc and now Hurricane actually costs mana (as it should, but the proc/buff should not exist anymore).
