This is supposed to `console.error` but it doesn't.

   We now have a consistent tree. Because this is a sync render, we
   will commit it even if something suspended.
  const finishedWork: Fiber = (root.current.alternate: any);
  root.finishedWork = finishedWork;
  root.finishedLanes = lanes;
  commitRoot(root, workInProgressRootRecoverableErrors);
   Before exiting, make sure there's a callback scheduled for the next
   pending level.
  ensureRootIsScheduled(root, now());
