title: Pop up window won't open in Ionic-v1 InAppBrowser
body: <p>I'm new to IONIC and trying to implement payment gateway in my Ionic app. I have everything set up in an external URL, only to load it to the app via InAppBrowser. All looks good especially with Mastercard until a customer decides to use Vis card to make payment which UNFORTUNATELY requires Verified by Visa (VBV/3DS pop up window) as part of its transaction flow.</p>
  
  <p><strong>NOW THE PROBLEM IS:</strong> pop window won't come up in InAppBrowser. I have tried to use iframe, its all the same thing. I have already looked into <a href="https://cordova.apache.org/docs/en/latest/reference/cordova-plugin-inappbrowser/" rel="nofollow noreferrer">Cordova Documentation on InAppBrowser</a> but not helping either.</p>
  
  <p><strong>in my config:</strong> 
  `</p>
  
  <pre><code>&lt;access origin="*"/&gt;
    &lt;allow-navigation href="*" /&gt;
    &lt;preference name="webviewbounce" value="false"/&gt;
    &lt;preference name="UIWebViewBounce" value="false"/&gt;
    &lt;preference name="DisallowOverscroll" value="true"/&gt;
  &lt;preference name="BackupWebStorage" value="none"/&gt;
  </code></pre>
