I think knock up needs clarity

When a champion is knocked up, does their hitbox move with their visual or does it stay where they were knocked up? (For what I know league is still a 2d game and when a champion is knocked up they visually move but hitbox is still on the ground)

If a knocked up champion's hitbox stay on its original spot, I think it need some sort of indicator, because when skillshot is fired toward the champion model it often just goes through them and the opponent can not see where the actual hitbox is.

This clarity issue had really bothered me, rito please fix it. (or maybe I live under a rock and this isn't an issue, if that is the case please inform me in the comment below)

edit: looks like my wording is horrible, let me say it in another way. Basically when a champion is knocked up/jumping/suspended by yasuo ult/held in air by suppression, their hitbox has no visual representation. as many comments have pointed out, it is usually on the ground. but since the champion is knocked up, often skillshots that looks like it hits visually nothing will land on the champion(which causes confuaion), and it is hard for the skillshot user to aim since they can't see the champion's actual hitbox(which indirectly protects the cc'ed champion from taking dmg).
