title: <label> for attribute selectors with duplicate IDs
body: <p>I'm using the bx-slider for a project I'm working on and I recently found out that it creates clones of the first and last input elements placing them in their respective spots to give the slider an "infinite" effect.</p>
  
  <p>This is great however when I'm using labels in the last one, it doesn't work as the for attribute on <em>both</em> labels will get the first input, which respectively is the clone.</p>
  
  <p>Is there any way I can use jQuery/CSS selectors in the for attribute? (Example: <code>&lt;label for="isActive28:last"&gt;</code>)</p>
  
  <p>Due to request, here is a quick jsfiddle to show what I mean: <a href="http://jsfiddle.net/YG9u9/1/" rel="nofollow">http://jsfiddle.net/YG9u9/1/</a></p>
