ScrollTrigger Snap + Smooth Scroll causes odd behavior

Note: I'm seeing the codepens linked are incorrectly positioned in the post. The one with peaches is ASScroll, the other is smooth-scrollbar When using some smooth scroll libraries through ScrollerProxy(), if a scrolltrigger has both `scrub: true` and `snap: 1`, instead of snapping back to the nearest position, the page does different things. ASScroll I originally found this when trying to use ASScroll. With ASScroll, the effect is that the page animates several pixels

I meant that using window.scrollY/pageYOffset to set positions of objects in WebGL causes a lag between DOM and WebGL position. I've just replaced ASScroll with your smooth scroll implementation on my basic DOM/WebGL sync demo and it does seem to work perfectly fine without any lag. And having looked through the ScrollTrigger source code, it does seem to end up just using window.pageYOffset. This is interesting! Codepen here: See the Pen 874833fdebc032bedd0cf61e9e
