title: Cannot set height with css units vw, vh or percentage
body: <p>I am setting the width and height of a <code>div</code> as a proportion of the viewport width and height respectively in a Ionic app. This works pretty fine on the explorer on my computer and on a device with Android 4.4. However, this propperty seems to have no effect on Android 4.2 (the height is limited to the text height). If I replace <code>vh</code> by <code>%</code> it keeps working on v4.4 but still not on v4.2.</p>
  
  <p>Here is my code</p>
  
  <p>HTML</p>
  
  <pre><code>&lt;body ng-app="starter"&gt;
      &lt;ion-pane&gt;
          &lt;ion-content ng-controller="langController"&gt;
  
              ...
  
              &lt;div id="language-selector" class="row"&gt;
                  &lt;h2&gt;Idioma&lt;/h2&gt;
              &lt;/div&gt;
  
              ...
  
           &lt;/ion-content&gt;
      &lt;/ion-pane&gt;
  &lt;/body&gt;
  </code></pre>
  
  <p>CSS</p>
  
  <pre><code>#language-selector{
      height: 10vh !important;
      padding: 0;
      background-color: #d1d3d4;
  }
  </code></pre>
  
  <p>How can I make this work on Android v4.2?</p>
  
  <p>Thank you in advance for your help.</p>
