title: Scrollbar is not showing in textarea for height:30px
body: <p>I am helping my friend today. He came across an issue that he wants a textarea to display in a height of 30px with scrollbar. Unfortunately if we give a height to the textarea the scrollbar is not shown but its working when we use the mouse scroller/keyboard up and down navigation keys.</p>
  
  <p>Css</p>
  
  <pre><code>&lt;style type="text/css"&gt;
  .txtarea { height:50px; overflow-y:scroll;  }
  &lt;/style&gt;
  </code></pre>
  
  <p>Html</p>
  
  <pre><code>&lt;textarea class="txtarea"&gt;&lt;/textarea&gt;
  </code></pre>
  
  <p>Please help.</p>
