[Gameplay] Skarner's recently buffed E providing incorrect passive duration

Skarner's E has two passive components to it; its cooldown is decreased equal to the duration of any hard crowd control you apply, and it provides you with access to your passive that is also equal to the duration of hard crowd control you apply.

Skarner's E was recently buffed such that the stun lasts 1.5 seconds, up from 1 second. This is a dramatic increase, however it appears that his E still only provides his passive for 1s rather than 1.5s. I wasn't paying attention to whether the cooldown of his E was also being properly reduced by 1.5s rather than 1s, but that is also harder to test.

To test this yourself, apply your E to an enemy (Gromp is the easiest) and then auto attack. You'll see that the passive buff falls off your buff bar about half a second sooner than the stun falls off Gromp.
