How to perform querySelectorAll on local dom in polymer dart 1.0.0.rc2?

I want to perform querySelectorAll on local dom of polymer element. I guess that doing simply:

querySelectorAll("some selector");

is not good idea because of all that mistic shady/shadow dom implementation details. I have tried several different ways:

var lst = Polymer.dom(root).querySelectorAll(".qtest");

gives wrapper around js array:

enter image description here

var lst2 = querySelectorAll(".qtest");

gives implementation of ElementList:

enter image description here

var lst3 = convertToDart(Polymer.dom(root).querySelectorAll(".qtest"));

is just simple List of elements:

enter image description here

In short: what's the proper way of calling querySelectorAll() that returns ElementList from local dom?

Polymer.dom(root).querySelectorAll('some selector');

Using this Polymer API ensures that you get what you want even when shady DOM or shadow DOM polyfills are used.
