/* These were earlier stateless functional components but had to be converted
since we need to use refs/findDOMNode to access the underlying DOM node to focus the correct completion,
something that is not entirely possible with stateless functional components. One could
presumably wrap them in a <div> before rendering but I think this is the better way to do it.
