title: Stop Event Propagation for Chrome Page Action
body: <p>I am building a chrome extension with page action. When i click on the icon of page action, it triggers the click event but the click also opens up chrome's predictive service or suggestions. It happens because i have no way of stopping the the event propagation to address bar which in turn captures the click event and shows the predictive service.
  I know users can disable the predictive service but thats not the solution. How can i make click event to stop the propagation or control that predictive service from my extension? chrome's onclick event handler only gets the tab but not the click event</p>
  
  <pre><code>function( tabs.Tab tab)
  </code></pre>
