           Summary: RegionNodeList should be invalidated upon style recalc

           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: HTML DOM
        AssignedTo: webkit-unassigned at lists.webkit.org

Right now, RegionNodeList is only invalidated when the node is added or removed. But it should also be invalidated whenever attribute changes, or for that matter, whenever style recalc needs to happen.

Also, I really don't think we should implement this as a dynamic node list. static node list would work much better because there's virtually no use case for using the same region node list while modifying DOM or styles.
