renderXXX 写法不支持

import React from "react";
import { definePage } from "@music163/tango-boot";
import { Page, Section, Button, Input, FormilyForm } from "@music163/antd";
class App extends React.Component {
  renderX(){
    return <Button>666</Button>
  }
  render() {
    return (
      <Page title={tango.stores.app.title}>
        <Section title="Section Title">
        {this.renderX()}</Section>
        <Section>
          <Button>button</Button>
          <Input />
        </Section>
      </Page>
    );
  }
}
export default definePage(App);

把这个丢到tango里, renderX里的组件可以拖拽,到另一个地方, 但表现上是复制,而不是移动
