Notice the flash. I'd expect `suspended` to be `true` during the high pri render.
renderingStartTime: number,
  
  last: null | Fiber,
  
  tail: null | Fiber,
  
  tailExpiration: number,
  
  tailMode: SuspenseListTailMode,
  
  
  lastEffect: null | Fiber,
|};
export function shouldCaptureSuspense(
  workInProgress: Fiber,
  hasInvisibleParent: boolean,
): boolean {
  
  
  const nextState: SuspenseState | null = workInProgress.memoizedState;
  if (nextState !== null) {
    if (nextState.dehydrated !== null) {
      
      return true;
    }
    return false;
  }
  const props = workInProgress.memoizedProps;
