title: Antd source map not supported in React
body: <p>I have an issue regarding the integration of Ant Design library in a CRA (create-react-app).</p>
  <p>After I have tried to integrate it as it is required in their <a href="https://ant.design/docs/react/use-with-create-react-app" rel="noreferrer">documentation</a>, without integration of Craco, I always get these 4 warnings:</p>
