[jQuery] Title attribute breaks the hover event?

[btwilkins]

I'm stumped...
I've got a hover event on a UL and it works perfectly, except when I
add a title attribute to an image inside that UL. When the tooltip
from the title attribute pops up, it reads it as you've hovered off
the UL. When I take the title attribute off, it works fine. Any ideas
on what's going on or how I can fix it? Here's the code...

-- jquery --
$("ul.edit").hover(
                        function() { $(this).children(".hidden").show("fast"); 
},
                        function() { $(this).children(".hidden").hide("fast"); }
);

-- html --
[code]

<ul class="edit">
  <li>
    <a href="..."><img src="..." title="foo"></a>
  </li>
  <li class="hidden">
    <a href="..."><img src="..." title="bar"></a>
  </li>
</ul>
