A web page to reproduce the problem

Overview: As specified in the shadow dom specification (http://w3c.github.io/webcomponents/spec/shadow/#focus): "A shadow host can delegate focus to its shadow root by assigning a boolean delegatesFocus flag to be true in ShadowRootInit dictionary". But this feature is not working.

Steps to Reproduce:
 - open the attached file (delegateFocus.html) in the latest nightly build
 - click on the text "Hello world"

Actual Results: nothing happens

Expected Results: The input field should receive focus.
