WCAG: 4.1.2: Use aria-roledescription on elements with a semantic role

Ensures that the aria-roledescription attribute is only used on elements with an implicit or explicit role values.

Inappropriate aria-roledescription attribute values that conflict with an element's implied or explicit role value can interfere with the accessibility of the web page. A conflicting aria-roledescription attribute value may result in no effect on the accessibility of the application and may trigger behavior that disables accessibility for entire portions of an application.

When aria-roledescription> attributes are applied to HTML elements not in accordance with WAI-ARIA 1.1, semantics conflict between the aria-roledescription value and the implicit or explicit element role value which may result in assistive technology products reporting nonsensical user interface (UI) information that does not correctly represent the intended UI experience.
