x-content 没有识别为 component 的子节点

import React from "react";
import {
  Upload,
  FormItem,
  FormLayout,
  FormButtonGroup,
  Submit
} from "@formily/antd";
import { createForm } from "@formily/core";
import { FormProvider, createSchemaField } from "@formily/react";
import { Button } from "antd";
import { UploadOutlined } from "@ant-design/icons";

const UploadButton = (props) => {
  return <Button icon={<UploadOutlined />}>上传图片</Button>;
};

const SchemaField = createSchemaField({
  components: {
    Upload,
    FormItem
  }
});

const form = createForm();

const schema = {
  type: "object",
  properties: {
    upload: {
      type: "array",
      title: "上传",
      required: true,
      "x-decorator": "FormItem",
      "x-component": "Upload",
      "x-content": UploadButton
    }
  }
};

export default () => (
  <FormProvider form={form}>
    <FormLayout labelCol={6} wrapperCol={10}>
      <SchemaField schema={schema} />
      <FormButtonGroup.FormItem>
        <Submit onSubmit={console.log}>提交</Submit>
      </FormButtonGroup.FormItem>
    </FormLayout>
  </FormProvider>
);

在存在x-component的情况下，x-content是不是应该识别为component的子节点？
