使用 defineModels 的时候应当和直接声明保持一致，是否能详细说明一下 passive 的意义

Describe the bug

# App.vue
<script setup lang="ts">
import { ref, watch } from "vue";
import HelloWorld from "./components/HelloWorld.vue";

const msg = ref({ name: 123, label: 789 });
const msg2 = ref({ name: 65, label: 456 });

watch([msg, msg2], () => {
  console.log(1);
});

[msg.value, msg2.value] = [msg2.value, msg.value];
</script>

<template>
  <HelloWorld v-model:msg="msg" v-model:msg2="msg2" />
</template>

// HelloWorld.vue

<script setup lang="ts">
let { msg, msg2 } = defineModels<{
  msg: number;
  msg2: number;
}>();

const onClick = () => {
  [msg2.value, msg.value] = [msg.value, msg2.value];
};
</script>

<template>
  <button @click="onClick()">adsfsdf</button>
</template>

第一次的交换，watch 只会监听到一次
当执行 HellowWorld 里的onClick 时，watch 会监听到两次

// 文档

我试了一下，如果编译后是这样的话，watch 监听到也是一次
所以到底是哪里出错了
