title: Ionic: scrolling up stops when using scrollIntoView
body: <p>I'm with a Ionic app which has a side menu where I've put some buttons in as an index for a large html content. When I click on sided menu button  <code>element.scrollIntoView(false)</code> that scrolls an <code>ion-scroll</code> container to the element.<br>
  The problem I've found is that I can scroll down and continue reading the html but I can't scroll up.<br>
  The ion-scroll definition:</p>
  
  <pre><code>&lt;ion-scroll delegate-handle="contentScroll" zooming="true" min-zoom="1.0" height="100%" style="height:100%" direction="['x','y']"&gt;
      &lt;div id="page-container" style="padding: 45px 5px 5px 5px;text-align: justify;"&gt;                                            
       &lt;/div&gt;
  &lt;/ion-scroll&gt;
  </code></pre>
  
  <p>A button definition:</p>
  
  <pre><code>&lt;ion-content ng-controller="ScrollCtrl as scroll"&gt; 
         &lt;button class="button" ng-click="scroll.to('markElementN')" menu-close style="width:100%"&gt;ElementN&lt;/button&gt;
  &lt;/ion-content&gt;
  </code></pre>
  
  <p>scroll.to function is:     </p>
  
  <pre><code>function(mark) {
    if (mark == undefined || typeof mark != 'string' || mark.length &lt; 1) {
      return;
    }
    var ob = document.getElementById(mark);
    if (ob) {
      ob.scrollIntoView(false);
    }
  }
  </code></pre>
  
  <p>¿anyone with the same issue?<br>
  I should add that I can scroll down and up again but not upper than the element I scrolled into view</p>
