bug#32850: 27.0.50; window-swap-states doesn't swap window prev/next-buffers

Gnus/5.13 (Gnus v5.13) Emacs/27.0.50 (x86_64-pc-linux-gnu)
For a long time I've been using my own implementation that swaps window states:
(defun rotate-window-buffers (&optional n)
"Exchange buffers in all windows N times.
With positive N, it uses the window order of `window-list'.
With negative N, does this in the reverse order."
(let* ((ws (window-list))
(ls (mapcar (lambda (w)
(list (window-buffer w)
(n (mod (or n 1) (length ws))))
(dolist (w (append (last ws n) (butlast ws n)))
(let ((l (pop ls)))
(set-window-buffer w (nth 0 l))
(set-window-point w (nth 1 l))
(set-window-next-buffers w (nth 2 l))
(set-window-prev-buffers w (nth 3 l))))))
Now I wanted to throw it away and to use window-swap-states
from Emacs core that should do the same. But after trying
I see that window-swap-states breaks the order of window buffers
for 'C-x <C-left>' (previous-buffer) and 'C-x <C-right>' (next-buffer)
because it doesn't swap window-prev-buffers and window-next-buffers.
Shouldn't window-swap-states also swap prev/next buffers?
