Check shade expansion fraction to allow animation

In compose, it seems that values doesn't get updated before the time of
the transition of UMO from QS to QQS. Therefore, the UMO is still marked
as if it's visible and animation is executed, which leads to the flicker
effect. Checking the shade expanded fraction and decide whether
animation is needed fixes the issue.
