Charts Exporting stops working on vaadin version 23.2.11

[homerstone]

Describe the bug

Exporting Vaadin Charts to SVG, PNG, etc. via the Exporting class works fine in Vaadin version 23.2.10, but stops working on version 23.2.11-23.3.6.

Expected-behavior

Using Exporting class allows to add a dropdown-menu to a chart containing buttons to export the chart in different formats.

Reproduction

• Download quick-start project (in my case the vaadin-version was 23.3.6)
• add code below to MainView.java
  -> exporting charts does not work
• set <vaadin.version>23.2.10</vaadin.version> in pom.xml
  -> exporting charts does work

My testing showed that it stops working on version 23.2.11.

@PageTitle("Main")
@Route(value = "")
public class MainView extends HorizontalLayout {
    public MainView() {
        add(createChart());
    }

    private Chart createChart() {
        Chart chart = new Chart(ChartType.COLUMN);

        Configuration conf = chart.getConfiguration();
        conf.setTitle("Reindeer Kills by Predators");
        conf.setSubTitle("Kills Grouped by Counties");

        ListSeries series = new ListSeries("Diameter");
        series.setData(4900,  12100,  12800,
                    6800,  143000, 125000,
                    51100, 49500);
        conf.addSeries(series);
        conf.setExporting(exportingOptions());

        return chart;
    }

    private Exporting exportingOptions() {
		Exporting exporting = new Exporting();
		exporting.setEnabled(true);
		exporting.setFilename("file_name");

		ContextButtonMenuItem png = new ContextButtonMenuItem();
		png.setText("Export png");
		png.setOnclick("function () {this.exportChart();}");

		ContextButtonMenuItem svg = new ContextButtonMenuItem();
		svg.setText("Export svg");
		svg.setOnclick("function () {this.exportChart({type: 'image/svg+xml'});}");

		ContextButton ctxBtn = new ContextButton();
		ctxBtn.setMenuItems(new ContextButtonMenuItem[] {png, svg});

		Buttons btns = new Buttons();
		btns.setContextButton(ctxBtn);

		exporting.setButtons(btns);
		return exporting;
	}
}

Probably related to vaadin/web-components#5080 which was backported and released in 23.2.11 (vaadin/web-components#5086)

Fixed by a PR for the web components. The fix will be back-ported to v24.0, v23.3, and v23.2.
