         highlight/focus ring on the TextView instead of the whole item, this is because there is a

         specific logic in HorizontalBreadcrumb when binding click event, the event is bound

         on the whole item directly and there are special a11y handling (check the

         `setAccessibilityDelegateCompat` call). Given we don't want the focus background on

         the item, we also need defaultFocusHighlightEnabled above and duplicateParentState

         below.  -->
