           Summary: getComputedStyle returns percentage values for left /
                    right / top / bottom
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Windows XP
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: CSS
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: jaffathecake at gmail.com


var div = document.createElement('div');
div.style.position = 'absolute';
div.style.top = '10%';
document.body.appendChild(div);
alert( window.getComputedStyle(div, null).top );

The above will alert '10%' rather than the pixel value.

Gecko / Presto will give the pixel value.

Webkit gives the pixel value for other properties (widht, height etc) and will
give the pixel value for left / right / top / bottom if the set value isn't a
percent, eg 10em.

The above bug exists in Safari, Chrome and Nightly r48199, although I have only
tested on Windows.

Jake.
