This is not possible, when the drawing area creates the LayerTreeHost it expects it to be initialized, because the initialize method is called from the ::create(). What would be do in LayerTreeHostGtk::setRootCompositingLayer() for example if we are not initialized yet? Do we need to check it on every single method?.
