bug#2815: 23.0.91; scroll-bar in *Calendar* buffer does not scroll through calendar but scrolls contents away

Hello!

In *Calendar* when I scroll downwards (upwards not possible) by  
dragging the scroll-bar the visible contents is scrolled away instead  
of showing other months.

It would be better to switch the scroll-bar off since it lies,  
indicating there would be more below the end of text or buffer mark  
in the fringe.
