    calendar: Allow keynav to day headers and week numbers
    
    While those elements cannot be activated, they still provide useful
    information to screen readers, so include them in the focus chain.
    For the same purpose, set a more verbose accessible name, given that
    it is not bound by the same space constraints as the visible label.
