- When we get a collapse before the layout happened in SystemUI,
don't expand the panel after the layout.
- Don't reset waitingToShow when coming out of sleep. This will cause
win.isVisibleOrBehindKeyguardLw to return false and then occluded
state will change rapidly from true -> false -> true, leading to
flickering in SysUI.
