There are flags for this. There is a flag to toggle “Microsoft Edge scrolling personality” in Edge and there is a flag to toggle smooth scrolling overall.
I've disabled smooth scrolling in Edge because of this, yes.
Nor scroll to top/bottom via the Home/End keys. In Firefox (or Chrome for that matter) it's quick enough that I don't mind the smooth scrolling, but in Edge it's comparatively and disconcertingly slow.
