Notice the flash. I'd expect `suspended` to be `true` during the high pri render.
return (
        <Suspense fallback="Loading...">
          <AsyncText ms={2000} text={text} />
        </Suspense>
      );
    }
    const root = ReactNoop.createRoot();
    await ReactNoop.act(async () => {
      root.render(<App text="Initial" />);
    });
    
    await ReactNoop.act(async () => {
      Scheduler.unstable_advanceTime(2000);
      await advanceTimers(2000);
    });
    expect(Scheduler).toHaveYielded([
      'Suspend! [Initial]',
      'Promise resolved [Initial]',
