In Vaadin Charts 2, when moving the Legend from its default place below the chart to appear above the chart:

myChart.configuration.getLegend().setVerticalAlign( VerticalAlign.TOP )

… the result is the Title being rendered as a layer hovering over the Legend.
How can I fix this, to not be overlapped?
