我尝试使用FirestoreDataConverter将对象转换为firestore数据，但似乎转换器仅适用于addDoc和setDoc操作，但当尝试将其与updateDoc操作一起使用时，它不会触发toFirestore函数。

可复制示例

interface Post {
  author: string;
  content: string;
}

async function addAndUpdatePost() {
  const colRef = collection(firestore, 'posts')
    .withConverter(postConverter);
  const post: Post = { author: 'Author', content: 'Content'};
  const docRef = doc(colRef);
  await setDoc(docRef, post);                      // Triggers toFirestore function
  const addedPost = (await getDoc(docRef)).data(); // Triggers fromFirestore function
  if (!addedPost) return;
  await updateDoc(docRef, addedPost)               // Does NOT trigger toFirestore function
}

const postConverter: FirestoreDataConverter<Post> = {
  toFirestore(post: Post): DocumentData {
    console.log("Went through to-converter");
    return { ...post};
  },

  fromFirestore(docSnap: QueryDocumentSnapshot): Post {
    console.log("Went through from-converter")
    return docSnap.data() as Post;
  },
};

预期控制台输出

Went through to-converter
Went through from-converter
Went through to-converter

控制台实际输出

Went through to-converter
Went through from-converter

这种情况特别发生在updateDoc上。如果我使用setDoc，它会像预期的那样工作。难道updateDoc不受支持吗？文档中似乎根本没有提到它。https://firebase.google.com/docs/reference/node/firebase.firestore.FirestoreDataConverter
