title: Angular 2 stops working on page refresh
body: <p>got a bit silly question, but can't work it out by myself.</p>
  
  <p>I've got an Angular 2 application with authorization, API calls, and stuff.</p>
  
  <p>When you load some content, let's say mysite.com/users for the first time - everything works fine. I get the api response and render the page.</p>
  
  <p>But when you just refresh the page - you get again the api response and the javascript works as expected, but the UI is not rendering any dynamic content (ngIf, ngFor, whatever).</p>
  
  <p>The only way to make it work again - get back to home page and then move to the old page again.</p>
  
  <p>Could you please let me know any advice or guide where to look for to aim this issue?</p>
