           Summary: DidMoveToNewDocumentAssertionScope shouldn't be
                    necessary
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: HTML DOM

DidMoveToNewDocumentAssertionScope is there to only ensure Node::didMoveToNewDocument
is eventually called by implementations in derived classes.

A better to way to ensure that Node::didMoveToNewDocument is always called is to simply call it directly.
Since only subclasses of Element and ShadowRoot override this virtual member function
and we already have a special case for ShadowRoot, we can de-vritualize for all non-Element cases.
