 While the convention for higher-order components is to pass through all props to the wrapped component, this does not work for refs. That's because `ref` is not really a prop — like `key`, it's handled specially by React. If you add a ref to an element whose component is the result of a HOC, the ref refers to an instance of the outermost container component, not the wrapped component.
