slideToggle in jQuery 1.3

slideToggle in jQuery 1.3


[repost from http://groups.google.co.uk/group/jquery-en]
I noticed in version 1.3 the slideToggle animation effect has been
modified with the vertical padding and vertical margin also animated
to create a smoother effect" so I decided to test this out.
It works great in Firefox but in IE 7 it's even less smooth than the
previous version. The vertical padding and margin actually jump rather
than slide, creating a noticeable jumping effect (you can see this on
the jquery docs example page - http://docs.jquery.com/Effects/slideToggle).
