It works for me, and doesn't obviously glitch in the sense of dropping frames, but it feels wrong. The animations all start really slow, and the curves are way off the curves of OS-native features that do a page-at-a-time swipe. Also, if you continuous scroll with the trackpad and backtrack your fingers even a little, it jumps back a section. Still, I am not sure it is easy to fix these issues given what the web platform offers today, and kudos for not blatantly dropping frames.
