title: Image is not clickable inside anchor only in IE7
body: <p>Html Structure </p>
  
  <pre><code>&lt;a&gt;
     &lt;span&gt;   &lt;!-- Span has width &amp; height --&gt;
     &lt;img&gt;
     &lt;/span&gt;
     &lt;span&gt; Some text &lt;span&gt;
  &lt;/a&gt;
  </code></pre>
  
  <p>Anchor is not clickable only in IE7, I know the issue happens because of hasLayout, if we remove height &amp; width of the span, it will work fine.</p>
  
  <p>But I need to make it work with out removing height &amp;  width.</p>
