 * This is mostly an internal hook that allows for an optional ref (normally

 * will return a MutableRefObject used for DOM manipulation in a custom hook
 * followed by a ref callback function that should be passed to the DOM node
 * that will ensure that both the optional `propRef` and hook ref are updated.
