 If `onmatch` returns a component or a promise that resolves to a component, this component is used as the `vnode.tag` for the first argument in the RouteResolver's `render` method. Otherwise, `vnode.tag` is set to `"div"`. Similarly, if the `onmatch` method is omitted, `vnode.tag` is also `"div"`.
