Notice the flash. I'd expect `suspended` to be `true` during the high pri render.
hasContext = true;
      pushLegacyContextProvider(workInProgress);
    } else {
      hasContext = false;
    }
    workInProgress.memoizedState =
      value.state !== null && value.state !== undefined ? value.state : null;
    initializeUpdateQueue(workInProgress);
    const getDerivedStateFromProps = Component.getDerivedStateFromProps;
    if (typeof getDerivedStateFromProps === 'function') {
      applyDerivedStateFromProps(
        workInProgress,
        Component,
        getDerivedStateFromProps,
        props,
      );
    }
    adoptClassInstance(workInProgress, value);
    mountClassInstance(workInProgress, Component, props, renderExpirationTime);
    return finishClassComponent(
      null,
      workInProgress,
      Component,
      true,
      hasContext,
      renderExpirationTime,
    );
  } else {
    
    workInProgress.tag = FunctionComponent;
