Menu 'mode' props doesn't work proprely

[snettah]

This code should display an horizontal menu, but an ugly vertical menu is displayed, the example come from ant design site.

https://ant.design/components/layout/

import { Layout, Menu, Breadcrumb } from 'antd';
const { Header, Content, Footer } = Layout;

export default () => (
  <Layout className="layout">
    <Header>
      <div className="logo" />
      <Menu
        theme="dark"
        mode="horizontal"
        defaultSelectedKeys={['2']}
        style={{ lineHeight: '64px' }}
      >
        <Menu.Item key="1">nav 1</Menu.Item>
        <Menu.Item key="2">nav 2</Menu.Item>
        <Menu.Item key="3">nav 3</Menu.Item>
      </Menu>
    </Header>
    <Content style={{ padding: '0 50px' }}>
      <Breadcrumb style={{ margin: '16px 0' }}>
        <Breadcrumb.Item>Home</Breadcrumb.Item>
        <Breadcrumb.Item>List</Breadcrumb.Item>
        <Breadcrumb.Item>App</Breadcrumb.Item>
      </Breadcrumb>
      <div style={{ background: '#fff', padding: 24, minHeight: 280 }}>
        Content
      </div>
    </Content>
    <Footer style={{ textAlign: 'center' }}>

  </Layout>
);

Ok just use dangerouslySetInnerHTML
<style dangerouslySetInnerHTML={{ __html: stylesheet }} />
