This makes scrolling behave as it should on Wayland. On X however, Emacs
now receives too many scroll events per scroll on certain mouses. On
Logitech MX master 3, every mouse wheel scroll is registered as a double or
triple scroll. I would guess this has something to do with its scroll
wheel, since it has an electromagnetic scroll wheel. Such issues do not
exists on Emacs 28 though, but I guess I could probably make it usable by
binding triple scroll to normal scroll.
