Kalista Rend CD Reset Bug [GAMEPLAY]

Okay, so rend is supposed to reset the cooldown if it kills a unit. It also is programmed to wait until autos that are in the air to reach their target before rending that target. But it doesn't wait to rend targets with spears in them already. In the situation where there is a low health target with a spear in it and a high health target with an auto attack in the air towards it, rend will kill the first target, reset the cooldown, then apply to the second target once the auto lands, and put rend on cooldown because it didn't kill it. I do not believe this is how it is intended to work. I have only played a few games as Kalista, but I have noticed this happening a lot and it is rather frustrating because you have to stop autoing if you want to make sure rend properly resets, which is a significant loss in damage later in the game.
