Kha'Zix R evo bug.

When playing Kha'Zix, upon dying after evolving your ultimate, your color scheme reverts to base, still. Why the hell is this still here? Is this a fucking joke? I don't even remember how many patches it's been since this bug began, it's not a complex bug, it's not difficult to reproduce whatsoever, every single game you evolve R and die, it reverts to the base color without fail, but it's still here. Can someone offer a reasonable explanation as to why this is still here, please, enlighten me.
