Firefox上的AngularDart失败，“receiver.webkitCreateShadowRoot未定义”

我有一个AngularDart应用程序，可以使用Javascript在Chromium和Chrome上正常运行 . 但在Firefox和IE中，我收到以下错误：

[14:36:14.648] "NullError: receiver.webkitCreateShadowRoot is undefined

这是我的foobarUI / pubspec.yaml：

name: foobarUI
description: A sample web application
dependencies:
  angular: 0.9.3
  browser: any
  json_object: any
  petitparser: any
  unittest: any
  foobar:
    path: ../foobarLib

我试图添加js，shadow_dom和web_ui模块，但它没有任何区别 .

我试图添加“useShadowDom = true;” （和假）到主dart文件，没有区别 .

从错误中可以看出，缺少对DOM shadow root的webkit支持，但为什么这个模块没有处理呢？

angular.dart.tutorial chapter_03示例出现相同的错误 . 这显然是Angular.Dart的一个问题 . Bug提交为：https://code.google.com/p/dart/issues/detail?id=15752
