Bug description

When user scrolls swiper with mouse\trackpad and when main part of scroll is done Swiper almost every time does a little movement in the same direction as scroll and then back. Looks very meh.
It reproduces with mousewheel + freemode(sticky) in in vertical mode. Drag and touch swipes are fine.

For me it looks like the error in mousewheel when you calculate scroll poisition and etc you may emit some phantom scroll event with some scroll momentum left and it scrolls a bit with the same direction and then goes back as expected.

Expected Behavior

To stop at snap point rock steady and solid.
