Flickering when slightly overscrolling
When i scroll slightly over a snap-point, this polyfill will go with the scroll, displaying the a part of the content that is further than the next snap-point and then snap back to the closest snap-point.
For example, i scroll down 2 1/4 elements. I then see the 3rd element. The scroll-snap is at the beginning of the 2nd element though. The polyfill thus is moving back there, but does so with a flickering. It goes back too far, then comes to a rest at the right position.
In Safari it appears to always go down to the next snap-point in the direction of scrolling. This prevents the flickering and is a more natural feel.
Browser: Chrome 46, but it's a general issue
I have fixed this and other issues in ckrack/scrollsnap-polyfill. I'm using a different approach there, which parses CSS values, supports more of the spec and includes smooth scrolling.
