I want to use app-datepicker in a lit-element based app and I am using rollup to build my app.

The problem is that rollup does not include app-datepicker in the build even though I have import 'app-datepicker' and am using the tag in one of my templates.

When I edit app-datepicker.js to include

export { customElementsDefine, Datepicker };

and then in my code do

import { customElementsDefine, Datepicker } from "app-datepicker";

and

customElementsDefine('app-datepicker', Datepicker);

rollup picks it up.

This might be related to #181

Applies to all because the problem is already in the build step.
