Fiddle E while invisible

Can anyone explain why Fiddle E bounces to me when im invisible, or in a bush that has a control ward (havent attacked anything for a few seconds now, so im in the fog of war). Like why does his E bounce to targets that cant even been seen. I have waited in bushes trying to surprise the Fiddle to kill him, only to have a random Fiddle E to bounce to me in a bush that was control warded, and then Fiddle knows im in that bush now because his E bounced to a target that literally cant be seen. I feel like this should be fixed so that Fiddle E can only bounce to nearby targets that can be seen, or something like that. It just feels like complete BS when it bounces to me in a control warded bush
