Nothing, I presume.  ‘set-window-buffer’ calls set_window_scroll_bars
just like ‘set-window-scroll-bars’ called it before.  You should see the
same "problem" with fringes and margins.  I always hated the ideology of
buffer-local values that override window-local values but would not dare
to question it in public.
