How to reproduce:

1. Open https://jsbin.com/kixoqexixo/edit?html,output
2. Scroll the area with the green rulers using your trackpad and with some velocity

What happens:
As soon as you stop scrolling and momentum scrolling kicks in the red rulers also start to scroll.

What is expected:
As long as the scroll was initialized by the inner nested scroll-snap container the ancestor should not be scrolled.

I think I fixed this in r259805. Can you test STP 105?

Yes it is fixed in STP 105. I tested it in STP 104... Sorry for the noise and thank you very much.
