While working on the DevTools profiler, I've noticed that durations are sometimes incorrect. This seems to be vaguely related to high/low priority state updates. Need to track this down more so I'm filing an issue for myself.
current: Fiber | null,
  workInProgress: Fiber,
  renderExpirationTime: ExpirationTime,
) {
  
  
  
  const hasContext = pushLegacyContextProvider(workInProgress);
  const hasPendingNewContext = prepareToReadContext(
    workInProgress,
    renderExpirationTime,
  );
  let shouldUpdate;
  if (current === null) {
    if (workInProgress.stateNode === null) {
      
      constructClassInstance(
        workInProgress,
