Steps to reproduce the problem:
1. Use a Windows 10 machine with a mouse whose software supports scroll acceleration
2. Open any webpage tall enough to scroll, without smoothscroll js (e.g., reddit.com)
3. Scroll the page with the mousewheel

What is the expected behavior?
Mousewheel scrolling should accelerate based on your mouse software's settings

What went wrong?
Scrollable elements are only scrolled one line at a time or as dictated by Windows' mouse scroll settings.

Did this work before? Yes 60something - there doesn't appear to be any way to check a chrome installation's update history

Chrome version: 63.0.3239.108  Channel: stable
OS Version: 10.0
Flash Version: 

I use an evoluent verticalmouse 4, whose software supports mouse scroll acceleration, similar to various Microsoft mice. Every so often, Chromium breaks this, almost like it stops listening to the scroll events.

This still works correctly in third party Chromium based software, like Discord ( Chrome/56.0.2924.87 )
