Scrollify Trembling on Chrome

Hello, thank you for this shared work. I would like to use Scrollify but I notice after some tests that on Chrome, when the content of a section is longer than the viewport, it causes problems. The snaps are done overall but when you go down a little in too long section and you go up quickly, it starts to shake. Not always but very often and it seems that the more we use it the more problems of tremors appear. I am using Chrome Version 65.0.3325.181 (Official Build) (64-bit) on a Imac. We can see the problem on the demo page (https://projects.lukehaas.me/scrollify/#configuration). It's really on overflow sections. I tried to restart Chrome but the problem persists, including with just a single open window.
