The ariaCurrent property of the ElementInternals interface reflects the value of the aria-current attribute, which indicates the element that represents the current item within a container or set of related elements.
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.
