           Summary: ScrollingStateNodes should keep track of their IDs
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: bdakin at apple.com


There is a HashMap in ScrollingCoordinatorMac that maps ScrollingNodeIDs to ScrollingStateNodes. The nodes themselves should keep track of this ID. Then the id can be used to make sure ScrollingStateNodes remove themselves from the HashMap when they are destroyed, and it will also be useful for associating ScrollingStateNodes with ScrollingTreeNodes over on the scrolling thread.
