react-router-dom hot reloading using create-react-app

I'm learning React and React Router. I created an app using create-react-app, and hot reloading worked well until I started using react-router-dom.

Here's my package.json:

{
  "name": "my-app",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "bulma": "^0.7.2",
    "react": "^16.6.0",
    "react-dom": "^16.6.0",
    "react-router-dom": "^4.3.1",
    "react-scripts": "2.0.5"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": "react-app"
  },
  "browserslist": [
    ">0.2%",
    "not dead",
    "not ie <= 11",
    "not op_mini all"
  ]
}

index.js:

import React from 'react';
import ReactDOM from 'react-dom';
import { BrowserRouter as Router } from 'react-router-dom';
import App from './components/App/App';

const render = () => {
    ReactDOM.render(
        <Router>
            <App />
        </Router>,
        document.getElementById('root')
    );
};

render();

if (module.hot) {
    module.hot.accept('./components/App/App', () => {
        render();
    });
}

App.js:

import ...

const Home = () => (
  <div>
    <p className="is-size-1">Home</p>
  </div>
);

class App extends Component {
  render() {
    return (
      <Switch>
        <Route path="/" exact component={Home} />
        <Route path="/guests" exact component={TodaysGuests} />
      </Switch>
    );
  }
}

export default App;

After encapsulating my app in a BrowserRouter component, hot reloading no longer works. I have to restart the server before I can see any changes. Refreshing the page doesn't work.

Is hot reloading possible? Is using something like react-hot-loader necessary?
