Sortables incompatible with table rows?

Sortables incompatible with table rows?


Hello--
I'm trying to create a drag and drop reorderable table using
Sortables. The HTML elements are table rows.
Regardless of THEAD and TBODY tags etc., the row (TR) being dragged
likes to jump about 150px vertically above the mouse position. This
appears to happen whenever the table is not the first element on the
page.
I've got some example code reduced to core elements for demonstration
purposes here (try it in Firefox):

I thought this could an issue with the code that gets the mouse
position code so I started to look into the mouse position code to see
if I could find anything to tweak there but got lost rather
quickly. :)
Anyone interested in helping debug this so we can get the appropriate
patch submitted?
Thanks,
