Angular2 Exception: TypeError el.createShadowRoot is not a function (Safari / Edge)

I have an angular2 application that works fine in Chrome and Firefox, but in Safari I get this error:

TypeError el.createShadowRoot is not a function

And similarly in Edge:

The object does not support the property or method 'createShadowRoot' at BrowserDomAdapter.prototype.createShadowRoot ( http: // localhost: 5000 / lib / angular2 / bundles / angular2.dev.js: 22893: 7 )

More from the edge: enter image description here

Am I missing any gasket or polymer?
