[Gameplay Bug] Tenacity Not Affecting Slow Duration
Server: NA
Type of Bug: Gameplay bug, Tenacity not affecting slow duration

Blitzcrank's W - Overdrive will still slow him for 30% for full duration (1.5 seconds) with Mercury's Treads or any other Tenacity item.

Steps to reproduce:
-
Buy Mercury's Treads or Zephyr.
-
Activate W - Overdrive on Blitzcrank.
-
Get slowed at the end of the speed boost.
Expected result: Slowed by 30% for 0.975s seconds.
1.50s * (100% - 35%) = 0.975s
Observed result: Slowed by 30% for full duration (1.5 seconds).
Reproduction rate: 10/10
System specs: AMD Phenom II CPU + Radeon HD 7870XT GPU + 6GB System RAM
I am unaware if this affects other champions or slows.
