title: jQuery :not(:first) not working in IE8, but does in FF and Chrome
body: <p>$('.divMapTab:not(:first)').each(...</p>
  
  <p>I've got 2 divs on my page, both with class of divMapTab.  In FF and Chrome, the code above only selects the 2nd instance of divMapTab, but in IE it selects them both.</p>
  
  <p>Am I missing a subtlety in how the :not or :first keywords work?</p>
