Without using setup syntax sugar, using templates and jsx playgrounds at the same time will result in an error（不使用setup语法糖情况下，同时使用模板和jsx演练场会报错）

报错信息：Identifier '_createVNode' has already been declared. (15:80)

复现demo：

<script lang="jsx">
import { ref } from 'vue'
export default {
  setup(){
    const msg=ref()
    const aa = () => <div>xxx</div>
    return {msg,aa}
  }
}
</script>

<template>
  <h1>{{ msg }}</h1>
  <component :is="aa"></component>
  <input v-model="msg" />
</template>

如果使用setup语法糖则没有此问题：

<script setup lang="jsx">
import { ref } from 'vue'
const aa = () => <div>xxx</div>
const msg = ref('Hello World!')
</script>

<template>
  <h1>{{ msg }}</h1>
  <component :is="aa"></component>
  <input v-model="msg" />
</template>
