My version of UI-Router is: 1.0.19(current stable lastest)

Bug Report

Current Behavior:

I am using angular-ui-router with Angular1 and ocLazyLoad.
In Internet Explorer11, I am getting the below error message while instantiate module ui.router.

SCRIPT5022: [$injector:modulerr] Failed to instantiate module majorApp due to:
Error: [$injector:modulerr] Failed to instantiate module ui.router due to:

For solving this problem, I added the below polyfill script.

<script src="//cdn.polyfill.io/v2/polyfill.min.js?features=default,MutationObserver"></script>

So it works.

Expected Behavior:

I think working without polyfill is needed as the last version v1.0.18.

Your solution did not work for me. I had to use this polyfill from mozilla.org

This has been fixed in core, but is waiting on ui-router/core@66a3244 to ship.

See ui-router/core#215
