* Merges multiple refs into a single callback ref.
*
* This hook is useful when you need to attach multiple refs (for example, a ref
* passed from `forwardRef` and a local ref from `useRef`) to the same node. It
* accepts an array of refs and returns a callback ref that, when attached to a
* node, assigns that node to every ref in the array.
