title: hover on table row firing when moving between cells
body: <p>I have noticed some weird behaviour in Chrome 15 and Safari regarding jquery hover events on a tablerow.</p>
  
  <p>What is happening is that chrome is firing the off/on event when I move my mouse from one cell to the next (while in the same row). As the hover is attached to the table row I would expect the on/off events to only fire when moving on/off the row.</p>
  
  <p>Please see my <a href="http://jsfiddle.net/WzHQb/1/" rel="nofollow">JSFiddle</a>.</p>
  
  <p>In the example, move the mouse to the point where one cell ends and another begins (where the colours change).</p>
  
  <p>The events seem to fire correctly in IE and Firefox but not Safari and Chrome. Maybe it is a bug in webkit?</p>
