title: Cordova Android not allowing to open whitelisted intent to fb-messenger
body: <p>I have an Ionic Cordova app for android which has a button to facebook messenger:</p>
  
  <pre><code>&lt;a href="https://m.me/my-fb-page" target="_blank"&gt;&lt;img src="assets/images/messenger.svg" /&gt;&lt;/a&gt;
  </code></pre>
  
  <p>When tapped, nothing appears on the screen. I keep receiving this error through logcat:</p>
  
  <pre><code>CordovaWebViewImpl: Blocked (possibly sub-frame) navigation to non-allowed URL: intent://user/xxxxxxxxxxxxx/?intent_trigger=mme&amp;nav=discover#Intent;scheme=fb-messenger;package=com.facebook.orca;end
  </code></pre>
  
  <p>I have cordova-plugin-whitelist installed.</p>
  
  <p>Content of config.xml:</p>
  
  <pre><code>    ...
      &lt;content src="index.html" /&gt;
      &lt;access origin="*" /&gt;
      &lt;allow-intent href="http://*/*" /&gt;
      &lt;allow-intent href="https://*/*" /&gt;
      &lt;allow-navigation href="*" /&gt;
      &lt;allow-intent href="tel:*" /&gt;
      &lt;allow-intent href="sms:*" /&gt;
      &lt;allow-intent href="mailto:*" /&gt;
      &lt;allow-intent href="geo:*" /&gt;
      &lt;allow-intent href="fb-messenger:*" /&gt;
      &lt;platform name="android"&gt;
          &lt;allow-intent href="market:*" /&gt;
          &lt;allow-intent href="fb-messenger:*" /&gt;
          ...
  </code></pre>
  
  <p>I have tried a number of options for allow-intent, access and allow navigation.</p>
  
  <p><em>The issue is not specifically related to facebook messenger, I have problems with opening other external (payment) apps as well</em></p>
