EsLint Plugin Lit A11y: no-redundant-role
Enforce explicit role property is not the same as implicit/default role property on element.
Some HTML elements have implicit roles. For example, a <dialog>
element has the implicit role dialog
.
For those elements, there's no need to define a role unless you need to explicity change the existing one.

attribute.
