Table says:

aria-activedescendant="ID_REF" | ul | Set by the JavaScript when it displays and sets focus on the listbox; otherwise is not present.Refers to the option in the listbox that is visually indicated as having keyboard focus.When navigation keys, such as Down Arrow, are pressed, the JavaScript changes the value.Enables assistive technologies to know which element the application regards as focused while DOM focus remains on the ul element.For more information about this focus management technique, see Using aria-activedescendant to Manage Focus.

But there is no activedescendant code on the example.

Suggest deleting that row of the table.
