[Gameplay] Kha'zix jump counts as airborne for Yasuo ult

Now I know what you're all thinking. This is impossible, we've talked about this a million times. Enemy airbornes don't count for Yasuo ult, only cc airborne. Well, I'm here to tell you it totally did the opposite for me. Whether or not this is an intentional feature, I don't know, but I sure hope to hell it is NOT.

So here's the situation. 4 of my teammates are about to get knocked up and ulted by Yasuo. I'm kha'zix staying at max leap range away from them. They're all piled together. (I have evolved leap by this point, so I'm VERY far away) So yasuo knocks all 4 members up and ults them. As they're knocked up, I begin my leap from max distance. DURING Yasuo ult I get there with my jump and am IMMEDIATELY included in the ult. I get stuck airborne and he kills me (as I'm on like 300 hp from last engagement). I was NOT in his initial knockup but I was KEPT airborne and damaged by his ult just from jumping in with leap. WHY?! I usually record all my games, but this was not one of them. Sorry for that, but this shouldn't be tough to reproduce. If only we had a SANDBOX mode to help you fix bugs RITO. But NOPE. No Cigar (see what I did there?).
