Change Dashboard section ARIA role to region

[rolfsmeds]

Description

vaadin-dashboard-section has the ARIA role="section", which is an abstract role (a bit like an abstract class) which should not be used directly.

Expected outcome

Instead, role="region", which corresponds to <section> should be used.

This was probably implemented as specified, mea culpa. The mismatches between ARIA roles and their HTML element name equivalents are fun :)
