        Fixes http://bugzilla.opendarwin.org/show_bug.cgi?id=5256
        Relayout during load causes duplicate plugin part.

        This was a problem with <OBJECT>s that contain an <EMBED>, if
        layout happened in the middle of the OBJECT but before the EMBED.

        No test case added, requires manual testing.
