title: How to open a new window from a link in a webview in a chrome-packaged app
body: <p>In order to show ads from a banner exchange, I'm loading a webview containing an iframe linking to the ads server. Through some javascript I can have the ad link target to be "_blank" so the ad would open in a separate browser window, otherwise it would open in the same small webview.</p>
  
  <p>However it doesn't work and I get this in the console:</p>
  
  <pre><code>&lt;webview&gt;: A new window was blocked.
  </code></pre>
  
  <p>Any ideas how to do this?</p>
