[Gameplay] Smart Cast With Range Indicators Not Working As Intended

A little background first, I tested this in a custom game on Live (5.7). I used Graves as my champion of choice and the bug could be reproduced 100% of the time. I am using windows 8.1, if you need any other computer related information I will provide it upon request.

The bug is triggered whenever another ability is hit while holding down an ability to see its range. For instance, if I was to hold down Q with graves it will show me the range of Q. But, if I hit W while holding Q it will activate Q like I released it. Other things in the game also have the same effect such as any ability held down then: a summoner spell, an active item, the shop button, and the recall button.

Steps To Reproduce:

1. Pick graves (I have not tested this on other champs yet)
2. Activate smart casting range indicators.
3. Hold Q then hit any other ability, summoner spell, or shop/recall key.

The result should be that Q activates without you letting go of the Q key.

The correct response the game should have when one ability is held down and then another is pressed is to simply show the range of the second ability. I hope this helps, if you have any questions feel free to ask.
