title: Angular 4 app not working on IE11 and edge
body: <p>I am working on angular 4 app and its working fine on all browsers except IE11 and edge, I check for solutions and added es15 support and added polyfills to support IE but its still not working properly.</p>
  
  <p>Issue : Not loading at first time on IE and loads after couple of refreshes but not fully.</p>
  
  <p>I already have done the polyfill fixes as mentioned <a href="https://stackoverflow.com/questions/46036097/angular-4-error-in-ie11">here</a></p>
  
  <p>Any help is appreciable</p>
  
  <p>Thanks</p>
