lux lazer targeted on allied champions

that was NAUT a bug heheheh. anyways let me explain:

You hovered over naut's profile pic on the left side of your screen and your curser changed to a blue target. That makes you target that champion, it would work the same if you hovered over anyone's but that's what happened. If you want, you can move the profile pics to the bottom over your minimap or i think there's a setting to disable their use as a targeter.

Edit: just read the text under the video link lol, so you already know what happened but that's not a bug. You can disable the feature i believe or just move them a bit out of the way.

It's because when you mouse over a portrait your champion will cast abilities at that person.
