title: Highcharts legend item hover event?
body: <p>I have a chart where I want some series not to be clickable in the legend, but others to be clickable. That was easy, because there was a legendItemClick event that I could make do nothing depending on the series. An example is here: <a href="http://jsfiddle.net/9PqyG/3/" rel="noreferrer">http://jsfiddle.net/9PqyG/3/</a></p>
  
  <p>My problem is that the mouse pointer still changes from the arrow to the clickable-link-hand-pointer, and I don't want anyone thinking that this is clickable. I know that I can change the itemHoverStyle parameter to make the arrow appear for all the legend items, but that will change it for every series. 
  Can I make this happen only for a particular series?</p>
