Webkit now returning percentages for more getComputedStyle properties

[mikesherov]

Strangely, if an element has css 'min-width' value and a css margin value that is a %, in Safari (Version 5.1.7 (7534.57.2)), the returned value for $(element) is the 'min-width' value!

            // A tribute to the "awesome hack by Dean Edwards"
            // WebKit uses "computed value (percentage if specified)" instead of "used value" for margins
            // which is against the CSSOM draft spec: http://dev.w3.org/csswg/cssom/#resolved-values
            if ( !jQuery.support.pixelMargin && rmargin.test( name ) && rnumnonpx.test( ret ) ) {
                width = style.width;
                style.width = ret;
                ret = computed.width;
                style.width = width;
            }
        }

        return ret;

Fix #12088, Safari 5 and more percentages in getComputedStyle

In particular, min-width and max-width are taunting the awesome hack. Closes gh-865.
