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.
markUpdate(workInProgress);
      } else {
        
        appendAllChildren(newInstance, workInProgress);
      }
    }
  };
  updateHostText = function(
    current: Fiber,
    workInProgress: Fiber,
    oldText: string,
    newText: string,
  ) {
    if (oldText !== newText) {
      
      const rootContainerInstance = getRootHostContainer();
      const currentHostContext = getHostContext();
      workInProgress.stateNode = createTextInstance(
        newText,
        rootContainerInstance,
        currentHostContext,
        workInProgress,
      );
      
      
      markUpdate(workInProgress);
    }
  };
} else {
