Aurelia dialog throws Access is denied error in IE11 and Edge when running in iFrame

[ItWorksOnMyMachine]

I'm submitting a bug report

• Library Version: 1.0.0-rc.2.0.0

Please tell us about your environment:

• Operating System: Windows 10

• Node Version: 8.8.1

• NPM Version: 5.5.1

• JSPM OR Webpack AND Version webpack 3.5.5

• Browser: IE11 and Edge

• Language: TypeScript 2.4.2

Current behavior: When using an Aurelia application embedded in an iFrame, when the DialogService's open method is called, then IE11 and Edge throw an Access is denied error inside aurelia-metadata's Origin.get method.

Expected/desired behavior: The expected behavior is that the dialog shows itself. This works fine in Chrome and Firefox, it only fails in IE11 and Edge.

• What is the motivation / use case for changing the behavior? The motivation is to be able to show an Aurelia dialog correctly when the application is running in an iFrame. Granted, it's an edge-case, but probably one that will happen as legacy apps start migrating to newer apps using frameworks like Aurelia.

Since you've pinpointed the problem, why not submit the issue in aurelia-metadata? I can dig into the issue, but I'll need the version of aurelia-metadata you are using.

You are probably opening a dialog passing a class for viewModel? If so a work around will be to use a app root relative moduleId.

@StrahilKazlachev, you rock! The switch to moduleId fixes this issue for me.
