Notice the flash. I'd expect `suspended` to be `true` during the high pri render.
workInProgress: Fiber,
  firstChild: null | Fiber,
  renderExpirationTime: ExpirationTime,
): void {
   
   
   
  let node = firstChild;
  while (node !== null) {
    if (node.tag === SuspenseComponent) {
      const state: SuspenseState | null = node.memoizedState;
      if (state !== null) {
        scheduleWorkOnFiber(node, renderExpirationTime);
      }
    } else if (node.tag === SuspenseListComponent) {
       
       
       
       
       
      scheduleWorkOnFiber(node, renderExpirationTime);
    } else if (node.child !== null) {
      node.child.return = node;
      node = node.child;
      continue;
    }
    if (node === workInProgress) {
      return;
