title: jQuery Mobile 1.4 header issue
body: <p>I just upgraded my project to JQM 1.4 and it looks like the header is ignoring the data-role="none" attribute if used on an  tag in the header.  This worked in JQM 1.3.2.</p>
  
  <p>Please see the jsfiddle and code below</p>
  
  <p><a href="http://jsfiddle.net/caseylmanus/VL4HX/21/" rel="nofollow">http://jsfiddle.net/caseylmanus/VL4HX/21/</a></p>
  
  <pre><code>&lt;div data-role="page" id="p1"&gt;
  &lt;div data-role="header" data-theme='b'&gt;
      &lt;a href="#p1" data-role="none"&gt;&lt;img src="http://upload.wikimedia.org/wikipedia/commons/thumb/d/dd/Back.svg/120px-Back.svg.png" style="height:15px"/&gt;&lt;/a&gt;
       &lt;h1&gt;Header&lt;/h1&gt;
  &lt;/div&gt;
  &lt;div data-role="content" data-theme='a'&gt;
      Some content here
  &lt;/div&gt;
  &lt;div data-role="footer" data-position='fixed'&gt;
       &lt;h4&gt;Footer&lt;/h4&gt;
  
  &lt;/div&gt;
  </code></pre>
