           Summary: didClearWindowObject may be dispatched when window
                    object is not cleared
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: jhoneycutt at apple.com


FrameLoader::receivedFirstData() calls DocumentWriter::begin(), which is responsible for clearing the window object before loading new content. If a frame is showing the initial empty document, and the URL we're transitioning to is in the same security origin, DocumentWriter::begin() will choose not to clear the window object.

After DocumentWriter::begin() returns, FrameLoader::receivedFirstData() dispatches the didClearWindowObject callback - whether or not the window object was cleared.
