Extracted from https://github.com/facebook/react/issues/12643.

We're currently diff a host node in the complete phase even if it has bailed out in the begin phase. By itself, this just means we're doing a little bit more work than necessary. But it also has some observable effects. In particular, https://github.com/facebook/react/issues/13424 (which by itself would be very rare and probably not worth fixing) is made worse because we end up committing update to inputs from another component.

I have a fix for this in https://github.com/facebook/react/pull/13423. Filing this for posterity.
if (updatePayload) {
      markUpdate(workInProgress);
    }
  };
  updateHostText = function(
    current: Fiber,
    workInProgress: Fiber,
    oldText: string,
    newText: string,
  ) {
    
    if (oldText !== newText) {
      markUpdate(workInProgress);
    }
  };
} else if (supportsPersistence) {
  
  
  const appendAllChildrenToContainer = function(
    containerChildSet: ChildSet,
    workInProgress: Fiber,
  ) {
    
    
    let node = workInProgress.child;
    while (node !== null) {
      if (node.tag === HostComponent || node.tag === HostText) {
        appendChildToContainerChildSet(containerChildSet, node.stateNode);
