dart - dart2js中的代码为get $ functions抛出NoSuchMethodErrors

Question

我的Polymer.dart网络应用程序在Dartium中运行良好，当使用pub build --mode=debug与dart2js一起编译并加载到Chrome中时，出现以下错误(重复七次)。

Resource interpreted as Script but transferred with MIME type text/plain: "http://confab.dev/index.html_bootstrap.dart". confab.dev/:10

由于源 map 似乎无法正常工作(它们已在Chrome中打开，并且我有.map文件)，所以我什至不知道我的代码的哪一部分导致了这种情况。

我尝试过在dart.js之前，在as the docs say之前以及之后在as this issue中都包含的interop.js。

看起来像dart2js中的错误。请提出问题，最好使用可复制的测试用例。
