           Summary: Assignment to style.border causes border-style and
                    border-color duplication
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
        OS/Version: Mac OS X 10.6
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: New Bugs
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: andrewss at vmware.com


When an element's style.border is set to "0", the border-style and border-color
attributes are set implicitly.  Repeatedly calling style.border = "0" causes
the implicitly border styles to be added to the element again, instead of
updating the existing value.

For example, after setting border.style = "0" twice.  The value of the style
attribute is:
border-style: initial; border-color: initial; border-top-width: 0px;
border-right-width: 0px; border-bottom-width: 0px; border-left-width: 0px;
border-style: initial; border-color: initial;

The border-style and border-color attributes are listed twice, and will be
listed again every time the style.border value is set.

A test case is attached.  This behavior is visible on Safari 4.0.5 and Chrome
5.0.342.9 beta on Mac OS 10.5 and 10.6
