[Gameplay] Renekton W Bug

I had been noticing some weird things after the 5.2 update. But only now after the 5.3 update have i figured out what it was. When you auto attack ANY enemy champion OR monster then quickly cancel the auto attack animation with Q and W at the SAME time it will result in the auto attack hitting the Q hitting but the W will do no damage will not apply the stun and will go on cool down (You are also stuck in a standing animation for about one second).

You will see in the video that this happens frequently enough to be a problem.. Another thing that you might see in the video is that the final test works perfectly the auto attack hits the Q hits and the W is still waiting its duration to be used. I believe this is because i started walking away. It seems that if you stand still it increases the odds of this bug happening. Thanks for helping guys hopefully this bug will be fixed soon!

Also just a side note you can see in the video that there is no stun indicator above the monsters head.
