WCAG: 4.1.2: Elements must only use allowed ARIA attributes

Not all ARIA role-attribute combinations are valid. This Rule checks that each role is supplied with allowed attributes.

Using ARIA attributes in roles where they are not allowed can interfere with the accessibility of the web page. Using an invalid role-attribute combination will, at best, result in no effect on the accessibility of the application and, at worst, may trigger behavior that disables accessibility for entire portions of an application.

When ARIA attributes are used on HTML elements that are not in accordance with WAI-ARIA 1.1, they conflict with the semantics of the elements which can cause assistive technology products report nonsensical user interface (UI) information that does not represent the actual UI of the document.
