7.10 Rammus Taunt, Delayed Effect Bug

The new Rammus taunt seems to have a slight delay before actually kicking in and making target champions attack you. In two matches against bots as rammus, I experienced multiple instances of taunting an enemy champion after which the target moved away from me for a brief period of time before moving towards me to auto attack. Similarly, taunted champions would occasionally stand totally still for a small time before moving towards me to auto attack. I do not recall experiencing this kind of behavior with rammus pre-7.10 taunt. It also didn't happen everytime, but often enough over the course of the games to be notable.

This slight delay seems to effectively lower the duration of Rammus's taunt by somewhere between .25-.5 seconds. Is anyone else experiencing this?

To reproduce, go into a game as rammus and try to taunt enemy champions. The issue most often occurred when taunting a champion running away.
