Renekton W bug (gameplay)

As Renekton, using W on a minion gives you the gold even if the minion dies After the animation has ended. I don't know if it's only hiding the next auto Attack animation or of it's registering the dmg delayed. To reproduce use W on a creep as Renekton when said creep has enough ho to survive it but not enough to survive an additional bug. Probably it's better to do it on a minion that's beeing damaged from allied minion/tower while your W occurs
