           Summary: [CSS Regions] Fix the lifecycle for the flow objects
                    and their renderers
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: abucur at adobe.com


Currently, the Regions implementation is WebKit doesn't respect the state machine described in the latest spec draft http://www.w3.org/TR/css3-regions/#cssom_view_and_css_regions . For example, getFlowByName will return a non-null value for un-existing named flows (neither flow-into/flow-from are specified for that name). Even more, a renderer will be created for that flow.
