    Clone the settings from another editor extension (same class).
    This method is called when splitting an editor widget.
    # TODO at the current estate this is not working

    .. note:: The base method does not do anything, you must implement
        this method for every new editor extension/panel (if you plan on
        using the split feature). You should also make sure any properties
        will be propagated to the clones.
