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.
workInProgress.effectTag |= Placement;
    
    
    
    workInProgress.child = mountChildFibers(
      workInProgress,
      null,
      nextChildren,
      renderExpirationTime,
    );
  } else {
    
    
    reconcileChildren(
      current,
      workInProgress,
      nextChildren,
      renderExpirationTime,
    );
    resetHydrationState();
  }
  return workInProgress.child;
}
function updateHostComponent(current, workInProgress, renderExpirationTime) {
