[GAMEPLAY] Warwick Ult Interaction

I've noticed that certain crowd control effects applied through auto attacks like garen's silence or leona's q stun go through warwicks new ult and cancels it. I could only think of these two champions with that kind of ability. So to reproduce the bug:

1. activate q on leona/ garen
2. target warwick
3. while moving toward warwick have him ult you
4. as soon as warwick gets in range for the suppress the cc activates and cancels the ult I was able to reproduce it about 90% of the time, sometimes you lose targeting when warwick ducks into a bush before ulting and garen's cc won't cancel warwicks ult
