title: with this.location.back() only url is getting changed ,it's not loading the correct tab
body: <pre><code> back() 
    {
      this.location.back();
    }
  </code></pre>
  <p>while loading the tab, changing the URL for that  particular tab manually:</p>
  <pre><code>  this.router.navigate([this.routerUrl], {queryParams:{q:'apps'} })
  </code></pre>
  <p>this.router.navigate is not registering the URL in history, since on press of back button only URL getting changed but it's not loading the correct tab inside parent page.</p>
