           Summary: Fix outline not rendering for composited divs with
                    overflow:hidden
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: mmaerean at adobe.com

The following div is rendered without the outline when compositing is activated using the transform property.
<div style="overflow:hidden; outline:solid 1px green; -webkit-transform:translateZ(1px);">text</div>

The outline is rendered when the overflow property is removed.

Removing the transform property causes the outline to be rendered no matter if the overflow property is present or not.

None of this happens if the overflow property is replaced with a box-shadow property.
If there is an outline and a box-shadow that is smaller than the outline, the visible outline is clipped to the rectangle of the box-shadow.
