[GAMEPLAY] Rengar Brush Leap Onto Blue Sentinel Cancels it's Attack Animation

If Rengar casts his Q: "Savagery" mid flight when leaping from the Blue Sentinel brush onto the Blue Sentinel it will cause the Attack Animation of said Blue Sentinel to be cancelled therefore making it seem as if Rengar gets Damage from nowhere

1. Go Into the Sentinel's brush
2. Leap onto the Sentinel using your passive
3. Cast your q mid flight so it activates after you land

I've had it happen to me about everytime I've tried it when going for the Red Side Blue Buff and I've had it happen several times at the Blue Side Buff aswell. Neither Skins nor Items appear to remove / alter this Issue.
