image-revert is another special, as indicated by bug#33631

Do you know why it currently moves point to the end of the buffer
in non-selected windows. I don't understand what causes this behavior.

Yes, better to keep every window's own point. Since usually I save
the selected window's point along with the window configuration, in e.g.
((window-configuration-1 selected-window-point)
(window-configuration-2 selected-window-point)
...)
this could be extended to save a mapping of all windows points, e.g.
((window-configuration-1 ((window-a point-a) (window-b point-b) ...))
(window-configuration-2 ...)
...)
But it's not a general solution. A general solution would be to save
such metadata in the window configuration itself.
