[GAMEPLAY] Heimer turrets drawing minion aggro

Unlike other abilities, turret basic attacks draw minion aggro towards Heimerdinger. I'm not entirely sure this is intended, and it makes his gameplay problematic since you have to juggle minion aggro far too often just from enemies walking near them. In order to reproduce this bug you must:

1. Place down a Heimerdinger turret near the minion wave.
2. Basic attack an enemy champion so your turret focuses him.
3. Walk into a brush to draw the intended aggro from the auto attack.
4. Walk back into the lane, your turret will be auto attacking the enemy champion, this will draw aggro toward you even though abilities are not supposed to draw minion aggro.

This happens in every game. It's possible this is an intended interaction, however, it seems a bit odd since Heimer's Q is not a spell blade effect like other abilities that are intended to draw minion aggro. His Q also does not stack fervor of battle, which again makes me think that it's not intended to be considered an auto attack, and should therefore not draw minion aggro.
