           Summary: Blending doesn't work if the parent stacking context
                    is a normal flow only element
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: CSS
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: rosca at adobe.com


Blending does not work if its parent, being also the stacking context that isolates blending, is a normal flow only element.

The consequence for software blending is that the parent element cannot create the transparencyLayer because it's not a self painting layer, and for accelerated blending the parent cannot become accelerated for the same reason.
