        this.layoutNode(optionalDiagramElementEvent, node, layoutConfigurator);
    }
    // resolve overlaps due to previous changes
    new OverlapsUpdater().update(diagram);
    // resize according to the content
    new ContainmentUpdater().update(diagram);
    // finally we recompute the edges that needs to
    for (EdgeLayoutData edge : diagram.getEdges()) {
