Edge scrolls three times as many lines per mouse wheel turn as it should.

I configured my mouse wheel to scroll 12 lines each turn. This works fine everywhere, except in Edge (and any other UWP app).

I made a short GIF to demonstrate this. In the GIF you can see I set my mouse wheel scroll to 12 lines. Then I open up Firefox (left) and Edge Beta (right). I turn the mouse wheel down exactly once on Firefox and once on Edge Beta. Firefox correctly scrolls from line 1 to line 12. Edge Beta scrolls from line 1 to line 32!
