[GAMEPLAY] riven hydra q not properly being applied for TLD and black cleaver

I might just be a whiny riven player, but i don't believe this is how Riven's q and hydra should be interacting. The bug only occurs when riven casts one of her Q's that isn't a knockup in place as well as uses hydra to animation cancel it. When riven casts one of her first Q's in place and animation cancels it with hydra by using hydra directly before she Q's right next to her target, it only applies one stack of black cleaver and only counts towards one of the three parts of damage required to trigger thunderlord's. The black cleaver debuff and the part of thunderlord's are properly produced when riven uses one of her Q's as a dash as opposed to doing it in place. To reproduce this, all you need to do is stand right next to a target and use your hydra and cancel it with one of your Q's that isn't the knockup. It can be reproduced every time if you properly cancel your hydra with Q. Also, i am referring to ravenous hydra, not titanic.
