           Summary: RenderObject::canHaveChildren()==false prevents shadow
                    renderer creation
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: HTML DOM
        AssignedTo: webkit-unassigned at lists.webkit.org

Some renderers return false for canHaveChildren().  So if we try to convert the legacy shadow DOM code to the new API, the shadow nodes won't have their renderers.  See Node::createRendererIfNeeded().
