            Bug ID: 216264
           Summary: Having an iframe as a descendent node shouldn't
                    require ElementRareData
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: DOM
          Assignee: webkit-unassigned at lists.webkit.org

ElementRareData is a pretty big data structure. Don't force its existence on every ancestor of an iframe.
