no-redundant-roles
Some HTML elements have native semantics that are implemented by the browser. This includes default/implicit ARIA roles. Setting an ARIA role that matches its default/implicit role is redundant since it is already set by the browser.
Rule details
The default options for this rule allow an implicit role of navigation to be applied to a nav element as is advised by w3. The options are provided as an object keyed by HTML element name; the value is an array of implicit ARIA roles that are allowed on the specified element.

}
Succeed
