Hi Robin, claiming it is a presentational effect appears to be at odds with
every accessibility API which provide distinct roles to identify the semantic
structures of tabs [1](tab, tablist, tabpanels) which are implemented across
OS's and platforms. They are provided because almost all UI languages have tab
widgets. tabs are not merely presentational they are UI controls and have a
role and states and properties that cannot be handled by CSS.
