Top 3 issues:

  1. Label in Name – The ARIA attribute aria-label is used in many instances to override a visible text label that would provide a descriptive name if it were not overridden.
  2. Content on Hover or Focus – Wherever tooltip functions are used, a mouse user is unable to hover over the tooltip content and the tooltip content cannot be dismissed without moving focus.
  3. Name, Role, Value – Custom widgets such as tab widgets are not properly defined with all required roles and states.
