Wukong ult

I ran into a bug while playing against wukong, in aram. The bug involved wukong being knocked up in the air and still able to ult. Everyone else in the game reacted even the wukong to him being able to ult while in mid air. The wukong said he was just tapping the r button to get his ult off before he died and he ended up ulting in mid air but staying in 1 spot until he landed then started going around
