title: Label tap event delay
body: <p>There is some difference in perfomance between using tap event on label and on button component. 
  Lets take for example this nativescript hello world app</p>
  
  <p><a href="https://github.com/NativeScript/template-hello-world" rel="nofollow">https://github.com/NativeScript/template-hello-world</a></p>
  
  <p>And especially this code</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;Page xmlns="http://schemas.nativescript.org/tns.xsd" navigatingTo="onNavigatingTo"&gt;
    &lt;StackLayout&gt;
      &lt;Label text="Tap the button" class="title"/&gt;
      &lt;Button text="TAP" tap="{{ onTap }}" /&gt;
      &lt;Label text="{{ message }}" class="message" textWrap="true"/&gt;
    &lt;/StackLayout&gt;
  &lt;/Page&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>When i am tapping fast on the button the UI is updated smoothly, but when i change the Button component with Label and try to tap fast there is some delay with updating the UI or some of the taps are not handled and the message property is not updated correctly.</p>
  
  <p>I am using android (5.0) genymotion and real device (Android 6)</p>
  
  <p>Nativescript: 2.2</p>
  
  <p>The "problem" occurs in nativescript angular2 too.</p>
