title: HTML5 Web Notification: Icon Image not shown if more Notifications will be created in short time
body: <p>I am using Web Notifications. Now it could happen, that 2 notifications will be generated shortly after another. In Chrome (newst version), sometimes the icon won't be shown.</p>
  
  <p>This happens ONLY if I use an internal image...</p>
  
  <pre><code>//this is a test icon
  for(i=0; i&lt;2; i++){
      new Notification("Test",{
          icon:"https://someInternal.png",
          body:"TEST"
      });
  }
  </code></pre>
