title: Polymer app-route redirect
body: <p>I'm using <code>&lt;app-route&gt;</code> in Polymer. Everything works fine, except redirection. I've read <a href="https://www.polymer-project.org/1.0/toolbox/routing" rel="nofollow">https://www.polymer-project.org/1.0/toolbox/routing</a>, the explanation seems to be clear, but for some reason it doesn't work the way I would want it. </p>
  
  <p>Somewhere down in the view I have an element...</p>
  
  <pre><code>&lt;script&gt;
      Polymer({
          is: 'user-auth',
          responseHandler: function(event) {
              var token = event.detail.response.d.token;
              if (token != '') {
                  localStorage.setItem('access_token', token);
                  this.set('route.path', '/hello');
              }
  
          }
      });
  &lt;/script&gt;
  </code></pre>
  
  <p>The problem is, it redirects to <code>/x/y/z/hello</code> instead of <code>/hello</code> as an absolute url. How could I make the redirect absolute?</p>
