title: WebKit doesn't paint background-color for entire width of final inline list item
body: <p>On our website <a href="http://www.dimagi.com" rel="nofollow noreferrer">http://www.dimagi.com</a>, the items in the jQuery menu near the top of the screen gain a background-color on hover.  The hover background-color of the rightmost list item ("About Us") is cut off at the very right edge of the text, seemingly only in WebKit (tested Safari and Chrome in Windows XP).</p>
  
  <p>Can anybody see what I might be doing wrong in the CSS?  Or is this some obscure WebKit bug?</p>
