Juri,

You could set `display-line-numbers' to 'absolute and run code below every
time the window is scrolled up/down (e.g. with a hook):

(save-excursion
  (move-to-window-line 0)
  (setq display-line-numbers-offset
           (* -1
              (line-number-at-pos))))

Notice that if `display-line-numbers' is 'absolute and narrowing is
enabled, you already get your desired behaviour.
