[jQuery] [treeview] Expand on link click

It looked like a link clicked would expand it AND the link would load.
But I've found that if the link is another page, there is some event
timing problem where it tries to open but then the new page loads
and the expand is lost.
You can see it here,

Note that the + and - still expand, but I want the whole link to do
the expanding.
thanks!!
