[GAMEPLAY] Riven still able to break CC post 7.2

Just finished a match, where I witnessed a Riven repeatedly breaking out of CC (stuns/roots from Veigar-E and Jhin-W) while a stun/root is in effect, via use of her E.

As in the following happens: Example

Stun effect occurs-> after hit and while stun is in effect Riven uses E ability (appears to nullify/break out of stun in the process)
