[ProgressBar] Fix: Media volume bar indicates a wrong value

Symptom:
Media volume bar shows non-zero value even during the mute state.

Root cause:
A request for updating progress of ProgressBar has 2 kind of updating
ways, animated and non-animated. If a non-animated request is invoked
before completing an animated request, the visual progress can be
overwritten by the old animated request. As a result, the visual
progress value becomes different from the actual value.

Solution:
A running animation on the primary progress should be canceled
before handling a new non-animated request.
