nit Let's use a named function so we don't see "Anonymous" in the tests?

Suggested change

const Grandparent = () => {
const ref = React.createRef();
return <Memo ref={ref} />;

const Memo = React.memo(ForwardRef);
const Grandparent = () => {
const ref = React.createRef();
return <Memo ref={ref} />;
};
