Emberjs integration testing on IE11

After upgrading to ember version 1.10, ember integration tests don't work properly on IE11. I have set rootElement property but still don't see the app attached to root element div so the tests couldn't execute. Same tests run fine on both chrome and firefox. Here is my configuration

App.reopen({
    rootElement: '#ember-testing'
});
App.setupForTesting();
App.injectTestHelpers();

• emberjs 1.10.0
• jquery 2.1.4
• qunit 1.18.0
• ember-qunit 0.4.0
