code: function mapUrlChangeHandlersToProps(props) {
    return {
      onChangeFoo: (value) => replaceInUrlQuery('fooInUrl', encode(UrlQueryParamTypes.number, value)),
      onChangeBar: (value) => replaceInUrlQuery('bar', value),
    }
  }
docs: Manually specify how to deal with changes to URL query param props.
  We do this since we are not using a urlPropsQueryConfig.
