由于vue模板编译已经导入_Fragment，jsx插件对插槽的判断会出现错误，导致fragment的内容转换为插槽，从而无法显示
例如编译代码：

<script lang='tsx' setup>
    import { Fragment } from 'vue'
    const Root1 = <>root1</>
    const Root2 = <Fragment>root2</Fragment>
</script>
<template>
  <Root1/>
  <Root2/>
</template>

结果：

import { createVNode as _createVNode2, createTextVNode as _createTextVNode, Fragment as _Fragment2 } from "vue";
import { defineComponent as _defineComponent } from 'vue';
import { unref as _unref, createVNode as _createVNode, Fragment as _Fragment, openBlock as _openBlock, 
 createElementBlock as _createElementBlock } from "vue";
import { Fragment } from 'vue';
export default /*#__PURE__*/_defineComponent({
  setup(__props) {
   // 出错，root1将不会显示
    const Root1 = _createVNode2(_Fragment2, null, {
      default: () => [_createTextVNode("root1")]
    });
   // root2转换正确
    const Root2 = _createVNode2(_Fragment2, null, [_createTextVNode("root2")]);

    return (_ctx, _cache) => {
      return _openBlock(), _createElementBlock(_Fragment, null, [_createVNode(_unref(Root1)), _createVNode(_unref(Root2))], 64);
    };
  }

});

单测补一下

[Amour1688]

packages/babel-plugin-jsx/test/snapshot.test.ts 整到这个文件里面吧

[beicause]

原来可以这样。

Suggested change

	import _Fragment from 'example'
	import { Fragment } from 'vue'

[beicause]

这样没改前也能通过测试，因为_Fragment是编译SFC多根节点模板时生成的

[Amour1688]

import { Fragment as _Fragment } from 'vue' 这样吧
