如何在 vaadin-flow 中正确指定对话框大小

I've tried setting the width and height of the dialog but it doesn't affect the DOM element only its childs (which doesn't look as expected)

    @Override
    public VerticalLayout createComponent(P item) {
                // this simply create a VerticalLayout
        VerticalLayout layout = super.createComponent(item);

        HorizontalLayout subLayout = new HorizontalLayout();
        subLayout.setWidthFull();
        subLayout.setDefaultVerticalComponentAlignment(Alignment.CENTER);

        this.button = new MSButton(this.colorClass, this.vaadinIcon);
        this.button.addClickListener(event -> {
            this.parent = item;
            this.grid.getDataProvider().refreshAll();
            this.dialog.open();
        });

        subLayout.add(this.button);
        layout.add(subLayout);

        return layout;
    }

    private void constructDialog() {
        this.dialog = new Dialog();

        H1 titleHolder = new H1(this.getDialogTitle());
        titleHolder.addClassName("mt-0");
        titleHolder.setWidthFull();

        H3 headerHolder = new H3(this.getDialogHeaderText());
        headerHolder.addClassName("mt-0");
        headerHolder.setWidthFull();

        HorizontalLayout headerRow = new HorizontalLayout();
        headerRow.add(headerHolder);
        headerRow.add(this.getDialogHeaderIcon().create());
        headerRow.setWidthFull();

        MSButton closeButton = new MSButton("Fermer", "success",
                VaadinIcon.CHECK_CIRCLE_O, event -> {
                    dialog.close();
                });

        HorizontalLayout footerRow = new HorizontalLayout();
        footerRow.add(closeButton);

        VerticalLayout footer = new VerticalLayout();
        footer.setDefaultHorizontalComponentAlignment(Alignment.END);
        footer.setAlignItems(Alignment.END);
        footer.setWidthFull();
        footer.add(footerRow);

        VerticalLayout container = new VerticalLayout();
        container.add(titleHolder);
        container.add(headerHolder);
        container.add(this.grid);
        container.add(footer);

        this.dialog.setWidth("700px");
        this.dialog.setHeight("500px");

        this.dialog.add(container);
    }

修复了使用 Lumo 主题而不是 Material one 的问题.
