[Bug 16389] New: resolved value for top/left/bottom/right doesn't match most browsers

https://www.w3.org/Bugs/Public/show_bug.cgi?id=16389

           Summary: resolved value for top/left/bottom/right doesn't match
                    most browsers
           Product: CSS
           Version: unspecified
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: CSSOM

I believe the CSSOM spec should be amended to include top/left/bottom/right in
the list of properties that return used value when display is not "none".

Currently, IE, FF, and Opera return the "used value" for top/left/bottom/right
when "display" is not "none". Webkit returns the "computed value".

There is an open bug for this in Webkit to do the same as the other browsers:
https://bugs.webkit.org/show_bug.cgi?id=29084 . One source of hesitation (and
rightfully so) is that the spec currently says this is the correct behavior. 

There are also open bugs for this in popular JS libraries:
http://bugs.jquery.com/ticket/10639
http://yuilibrary.com/projects/yui3/ticket/2529799

Having the used value returned is a very useful operation. It's why JS libs are
asking for it and a majority of browsers are doing it this way. It'd be great
if the spec matched this reality.
