Catching Cross Domain JS Errors in IE11

By default JS errors originating on different domains aren't passed to window.onerror handler - Although I don't think this happens on versions of IE below 10 (or maybe 11). Instead they get just a basic "Script Error" on Line 0 message.

In most browsers you have to set crossorigin="anonymous" attribute on the script and return CORS headers on the script and then these errors will be caught.

However this doesn't seem to work on IE11. Is a different technique required?

Thanks for the feedback Kevin. IE does not currently support the crossOrigin attribute but it is something that is on our backlog.
