role-supports-aria-prop

Warns when an ARIA property or state is not in the WAI-ARIA role definition's set of supported states and properties for the element's computed role — e.g. aria-pressed on role="heading".

The names of ARIA attributes are compared as no-unknown-attr compares names (see its "Attribute name case" section): ARIA-LABEL is the same attribute as aria-label where the DOM treats attribute names as case-insensitive, such as on an HTML element, and a different one where it does not, such as on an <svg> element in JSX.

Split out of the former wai-aria-disallowed-props rule, alongside no-prohibited-naming and element-supports-aria-prop.
