KHA invis

So i'm not sure if this is a bug, but runaans can hit targets you dont see, say im kha and go invis the enemy teams kog will be autoing me still... i havent looked into it but does runaans hit you if you're in a unwarded bush? it seems like auto attacks shouldnt hit you if you're invisible because they're auto attacks. (as in kog is autoing someone else but the runaans is targeting me as kha (no i wasn't hit with his r))
