Using HTML5 data-* attributes in Vaadin?

Vaadin 6 / 7 / 8

Does Vaadin support adding global data attributes as described here?

Example:

<ul>
	<li data-type="fruit">Apple</li>
	<li data-type="fruit">Orange</li>
</ul>

Not really, but especially in Vaadin 10, there’s nothing that’s preventing you from adding them.
