role-supports-aria-props
Enforce that elements with explicit or implicit roles defined contain only aria-* properties supported by that role. Many ARIA attributes (states and properties) can only be used on elements with particular roles. Some elements have implicit roles, such as <a href="#" />, which will resolve to role="link".
Rule details
This rule takes no arguments.
