Stencil - polyfill issue - when import from npm

Hello guys,
Steps:

1. new stencil project, build it, the dist/ and loader/ folders generated
2. new create-react-app where the project created at 1) is used like stencil suggest:

import { applyPolyfills, defineCustomElements } from 'test-components/loader';
		applyPolyfills().then(() => {
			defineCustomElements();
		});

3. looks good in all browsers except IE. The polyfill is not applied in IE11 (Error: ‘Promise’ is undefined).
4. if I use the scripts in index.html it works good

Is that a known issue in Stencil or am I doing something wrong (what?)?
