Trackpoint-scrolling on W10: Firefox much smoother than Chrome

[ModelMman]

Tested on both a T410s with classic dome, and a T450s with modern dome, Firefox is much smoother than Chrome when it comes to mid-button Trackpoint scrolling on Windows 10.
On my Windows 7-install on a T420 the scrolling is smooth in both browsers, so I thought this was Win10-issue, but I guess not.

Try scrolling with both and tell me what you think!
