I'm submitting a bug report

• Library Version: 1.3.3

Please tell us about your environment:

• Operating System: Windows 10

• Node Version: 8.5.X

• NPM Version: 3.8.9

• JSPM OR Webpack AND Version Webpack 3.12.0

• Browser: Edge Mobile 44.X from UWP

• Language: javascript

Current behavior: Webpage does not load on any page because edge is failing on index.html when we call

<script src="{{basePathToken}}/dist/vendor-bundle.js"></script>
<script src="{{basePathToken}}/dist/polyfill-bundle.js"></script>

In which the polyfill.js fails giving this error:

Expected/desired behavior:

• What is the expected behavior? Any page of the website should load

• What is the motivation / use case for changing the behavior? possible browser not supported ?

I might add that it worked fine on an earlier version of edge mobile until the microsoft update a week or so ago
