.slideUp() not shrinking padding-bottom

[anonymous]

When using .slideUp() in v1.8.0, the bottom padding does not shrink as expected. The padding can be viewed in the inspector as the element v..e...r...y slowly slides up. See this fiddle: ​http://jsfiddle.net/9wPad/1/

If you change the jQuery version to 1.7.2 it works correctly. Able to repro in Chrome and FF latest, at least. I am using Windows 7.

I posted a question on StackOverflow here: ​http://stackoverflow.com/questions/12170889/jquery-slideup-not-shrinking-padding-bottom-value

Not sure why it filed as anonymous, but I filed this.

+1, a minimum ​fiddle shows that the paddingBottom is simply removed at the end of the animation and not animated as it should with the rest of the height.

A temporary workaround is to pass the borderTopWidth, paddingTop, height, paddingBottom and borderBottomWidth to .animate(). ​fiddle

It seems to be fixed in jQuery 1.8.1 ​fiddle.
