title: Links inside iframe (not in popup) doesnt work
body: <p>I have gone through other similar issues to solve this particular issue, but somehow in this case all the solutions are not working.</p>
  
  <p>So here is my the question with example snippet:</p>
  
  <p>I have an html file which looks like this:</p>
  
  <pre><code>&lt;div id="portalRight"&gt;
      &lt;a target="_blank" href="http://ictforu.com"&gt;   &lt;!-- this link works , it opens up another tab --&gt;
      &lt;ul id="subtabnav"&gt;
          &lt;li class="datasetTab"&gt;
              &lt;a href="#"&gt;dataset&lt;/a&gt; &lt;!-- Click on this will trigger the dataset iframe to be loaded thru a servlet call  --&gt;
          &lt;/li&gt;
          &lt;li class="obsGraphTab" data-bind="css: { disabled: !aekos.subTabViewModel.graphTabsEnabled() }"&gt;
              &lt;a href="#"&gt;Observation Graph&lt;/a&gt;
          &lt;/li&gt;
          .....
      &lt;/ul&gt;
  
      &lt;div id="dataset"&gt;
          &lt;iframe id="dataset-frame" class="graphiframe" seamless sandbox="allow-same-origin allow-scripts"&gt;&lt;/iframe&gt;
      &lt;/div&gt;
      &lt;div id="testViewer"&gt;
                  &lt;iframe id="test-viewer-frame" class="graphiframe" seamless sandbox="allow-same-origin allow-scripts"&gt;&lt;/iframe&gt;
      &lt;/div&gt;
  
  &lt;/div&gt;
  </code></pre>
  
  <p>As you can see my <code>iframe</code> isn't a popup but appears under a <code>div</code> element: <code>iframe</code> contents are filled using a servlet when the link is clicked.</p>
  
  <p>My <code>iframe</code> has base tags (base <code>target="_parent"</code>)under header of the <code>iframe</code>.</p>
  
  <p>I have used <code>&lt;base&gt;</code> tag to specify the behaviour and also link has <code>target="_blank"</code>, but my links doesn't work at all.
  Same link works outside the iframe.</p>
  
  <p>example iframe :</p>
  
  <pre><code>base target="_parent" /base 
  </code></pre>
  
  
  
  <p>body content: </p>
  
  <pre><code>a target="_blank" href="http://ictforu.com" /a 
  </code></pre>
  
  <p>this link doesn't work, clicks are ignored.</p>
  
  <p>Any help is much appreciated.</p>
  
  <p>Sorry had some editing issues with the html tags earlier.</p>
  
  <p>Thanks,
  Madhu</p>
