Ticket #3030 (closed bug: invalid)
hover doesn't work with image maps
|Reported by:||nene||Owned by:|
For some reason you can't do use hover() method to associate onmouseover and onmouseout event handlers with area elements of imagemaps. But assigning handlers directly to onmouseover and onmouseout attributes of the area element works just fine.
I didn't found a bug report on this, although the tooltip plugin in this same repository has implemented a workaround  for it. So it clearly must be an issue.
