title: Background color on input type=button :hover state sticks in IE
body: <p>I have an input type=button with a background color set and a different one on :hover - see <a href="http://jsfiddle.net/hc2Eu/3/" rel="noreferrer">http://jsfiddle.net/hc2Eu/3/</a></p>
  
  <p>In IE (all versions) - when I mouse down on the button, move off the button, then mouseup - the background color stays in the :hover setting until you mouse over it again.</p>
  
  <p>Is there some workaround for this? Preferably not with js? (IE6 not necessary)</p>
