Maokai instant sapling toss bug

Hi, I was just playing with the new maokai and I noticed something very buggy, if you use his passive on a target while casting sapling toss the sapling will instantly show up in the cast location without playing the toss animation. this is how to replicate what I did

1. Have sap magic up with maokai at less than 95% hp (so you can consume the buff)
2. Press E on a location within the range of the ability
3. the second you press E mash R-click or A-click on an enemy target. the sapling will instantly appear in the place you cast the ability on and will act like any other sapling its not some visual bug or anything. ps doesn't work if you auto->e has to be e-> auto. gg plz fix tyty :D
