title: Hide tabs in sub pages in Ionic 2
body: <p>I try to hide tabs on all my subpages in my app. 
  I use this :</p>
  
  <pre><code>&lt;ion-tab [root]="MyPage" tabsHideOnSubPages="true" ...&gt;&lt;/ion-tab&gt;
  </code></pre>
  
  <p>When I run ionic serve; it's work. 
  But when I try to run it on my devices, my tabs aren't hide in the sub pages, and I can't use it.</p>
  
  <p>Someone has an idea to finally hide my tabs in my devices ? </p>
  
  <p>[update]
  In my child page I have a google map. If I delete it I don't have my problem anymore. </p>
  
  <p>Child page .html : </p>
  
  <pre><code>&lt;ion-header&gt;
    &lt;c-header&gt;&lt;/c-header&gt;
  &lt;/ion-header&gt;
  
  &lt;ion-content&gt;
    &lt;div id="map"&gt;&lt;/div&gt;
  &lt;/ion-content&gt;
  </code></pre>
  
  <p>Child page .css : </p>
  
  <pre><code>#map {
    height: 50%;
  }
  </code></pre>
