[GAMEPLAY] Cassiopeia - Ultimate Stun Duration Indicator is invisible

When playing Cassiopeia , if you use Petrifying Gaze [R] on a target that is standing on top of Miasma [W], the stun indicator (small white bar underneath health bar that shows the length of CC) is no longer visible. The indicator is only visible when there is no Miasma [W] underneath the target. The stun duration is not changed.

1. Place Miasma [W] underneath a target.
2. Use Petrifying Gaze [R] on that same target, while Miasma [W] is still active.
3. Observe the absence of the CC Indicator underneath the target's health bar while stunned.

This bug was consistently reproduced in a Practice Tool match against Teemo Dummy Targets. I have not tested this in a normal match. Please see attached screenshot of two targets under the effects of Petrifying Gaze [R]; one target is on top of Miasma [W], the other is not.
