This is now against how IE9, FF3.6+, and Opera implementation of getComputedStyle() for margins. Open up the following jsfiddle in FF3.6+, Opera, and IE9: http://jsfiddle.net/u4F8m/9/

It is also against the CSSOM editor's draft: http://dev.w3.org/csswg/cssom/#resolved-value
http://www.w3.org/TR/css3-values/


It also now makes margin inconsistent with how padding, width, and height work for resolved values in Webkit itself.

I would also argue that "Having getComputedStyle return the size of the gap between the element's edge and the associated edge of its container is just not a *useful* operation." is not true. It's very useful to now the exact pixel dimensions of a box. Why would I ever want to know that a margin is "10%"? 10% of what? The actual pixel value used is way more relevant.

Please consider reopening and reverting this change.
