FakeClock currently doesn't work well with Espresso and Compose UI
tests because view interactions in both frameworks intentionally idle
the main looper to handle pending UI effects. However, this also
advances playback progress even though we want to deterministically
trigger progress from the test itself.
To solve this problem, we can detect the idling Robolectric call and
postpone any further updates until we leave this state.
