title: bootstrap 2.3.2 popover html content issue
body: <p>I'm trying to populate a <code>popover</code> dynamically through </p>
  
  <p><strong>JAVASCRIPT</strong></p>
  
  <pre><code>$("[data-bind='popover']").popover({
   trigger: 'hover',
   html: true,
   content: function(){ 
    return "&lt;img src="+$(this).data('content')+" /&gt;";
   };
  });
  </code></pre>
  
  <p><strong>HTML</strong></p>
  
  <pre><code>&lt;a href="myreference.html" data-bind="popover" data-content="mylinktoimage"&gt;Brick&lt;/a&gt; 
  </code></pre>
  
  <p>the problem is that if I set <code>width</code> and <code>height</code> inside the <code>img</code> <code>tag</code> inside <code>js</code>, the <code>popover</code> shows up. If I don't set them, first of all the anchor <code>&lt;a&gt;</code> the <code>pointer cursor</code> "vibrate" and the <code>popover</code> is not shown. </p>
  
  <p>What problem can this be?</p>
