Evelynn and Spectating Games

I'm not sure if someone has mentioned this before, but earlier I was spectating a friend's game and one of the teams had an Evelynn Jungle. Because she was in the game, every time she was in stealth, the game got the hazy look and muted sound effects like if you are playing Eve. This was even if she was not the focus of the camera. It made it really annoying to try and spectate the game.
