animate is not calculating the margin property correctly in jquery 1.4.4

[nsimeonov@…]

$(this).stop().animate({ width:"250px", height:"250px", margin:"0" }, 200);

Instead of changing the margin from 25 to 0 in 200ms animate immediately set it to 0.

This script works fine in 1.4.2

I can send you 2 identical demo pages demonstrating the bug - only difference is which jquery lib they reference. The page referencing 1.4.2 works fine, the one referencing 1.4.4 when animating the image resets the margin to 0 on step 1 causing the images to the right to jump to left or right.

Could you please submit a complete test case on  jsFiddle.net so we can evaluate this bug further?. Furthermore if you could also try it out using jQuery Git just to see if the behavior has been corrected there that too would be of great benefit.

The documentation on  animate() is rather clear as it states:

Shorthand CSS properties (e.g. margin, background, border) are not supported. For example, if you want to retrieve the rendered margin, use: $(elem).css('marginTop') and $(elem).css('marginRight'), and so on.
