Comment (by afercia):

 Noticed an edge case where the ARIA tabs markup is rendered even if there
 are no visible "menu" and "router" tabs. Learned the state attributes
 contain information on the two menus and it's possible to additionally
 check for them to better determine when the ARIA tabs markup needs to be
 rendered.

 [attachment:"47149.7.diff"] uses this approach to improve the related
 conditional checks and remove a no longer necessary conditional check.
