 *
 * This component uses `findDOMNode` which is deprecated in React.StrictMode.
 *
 * Helper component to allow attaching a ref to a
 * wrapped element to access the underlying DOM element.
 *
 * It's highly inspired by https://github.com/facebook/react/issues/11401#issuecomment-340543801.
 * For example:
 * ```jsx
 * import React from 'react';
 * import RootRef from '@material-ui/core/RootRef';
 *
 * function MyComponent() {
 *   const domRef = React.useRef();
 *
 *   React.useEffect(() => {
 *     console.log(domRef.current); // DOM node
 *   }, []);
 *
 *   return (
 *     <RootRef rootRef={domRef}>
 *       <SomeChildComponent />
 *     </RootRef>
 *   );
 * }
 * ```
 *
 * @deprecated
