title: Modifying text in resetZoomButton doesn't work - highcharts
body: <p>I have been trying to modify the text for <code>resetZoomButton</code> using the theme option as follows:
  <a href="http://jsfiddle.net/xurXt/" rel="nofollow">http://jsfiddle.net/xurXt/</a></p>
  
  <p>However, the new text seems to take effect only when I hover over the zoom button. </p>
  
  <p>What could be wrong here?</p>
