Chart not rendering in IE11 about highcharts-chart

[avdaredevil]

So I found it, it was the _loadingUpdate key in the main behavior. Thanks for your issue!
The library should be completely working on IE11.

If you like the library, don't forget to leave a star/donate!

Hey @jpnkicker14. According to the compatibility chart, IE11 shows HTML imports as unsupported (which is critical for Polymer to work).

Now you can get that functionality via a Polyfill, and that should fix it!

If you're using any ie browser below 11, the polyfills will not completely work [marked as ~ on the Polyfill Compatibility chart].

After debugging further, I've realized IE is simply not parsing the JS correctly in Strict Mode. However by making it non-standard mode, and ES5'ing (commit 8860c93) the demo page, it loads on IE.

Unfortunately the published library cannot exist without "use strict";
So the error in the console:

SCRIPT1046: Multiple definitions of a property not allowed in strict mode
In File highcharts-behavior.html

Needs to be fixed before proper compatibility is available for use. I cannot see why that error should exist, as I do not re assign a variable twice. However, I've made the demo workable, by applying the solution aforementioned.
