useForm's initializing and useField's formInitializing do not agree with each other on load

[tyteen4a03]

Describe the Bug

I don't know if this is a bug or intentional behavior, but useForm()'s initializing and useField's formInitializing do not agree with each other when the form is being loaded. This component highlights this behavior:

const TestClientField: UIFieldClientComponent = ()  => {
  const { initializing } = useForm();
  const { formInitializing } = useField({
    path: '',
  });

  if (initializing !== formInitializing) {
    console.log("initializing != formInitializing!", initializing, formInitializing);
  } else {
    console.log("initializing == formInitializing", initializing, formInitializing);
  }

  return <>test</>
}
