           Summary: Widgets should hold a WeakPtr to their parents
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2

          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: bfulgham at webkit.org

We don't have a parent/child destruction notification mechanism for Widgets and their enclosing ScrollViews. We should allow the Widget to hold a WeakPtr to the parent ScrollView so we can gracefully handle cases where the ScrollView has been removed from the current document by the Widget is still pending a final move operation.
