ElementInternals.ariaRequired
The ariaRequired property of the Element interface reflects the value of the aria-required attribute, which indicates that user input is required on the element before a form may be submitted.
Note: Setting aria attributes on ElementInternals allows default semantics to be defined on a custom element. These may be overwritten by author-defined attributes, but ensure that default semantics are retained should the author delete those attributes, or fail to add them at all. For more information see the Accessibility Object Model explainer.
