    inputMethod: Use update-preedit-with-mode signal
    
    This signal announces the preferred commit mode of the preedit text when
    the input context is reset. Keep this mode around, and ensure to honor this
    mode (e.g. maybe commit the preedit string) whenever the input method would
    be reset.
    
    This is delegated to the internal layers, so propagate this mode via
    clutter_input_method_set_preedit_text().
