What steps will reproduce the problem?
(1) Go on the page mentioned above or any other page that has a sticky navigation (Javascript adds class to element when scrolling)
(2) Fast Scroll down and up with the mouse wheel
(3) You will notice that at certain points, you won't be able to scroll anymore. It just blocks you from scrolling further (Keep the mouse on the same spot and scroll fast up and down)

What is the expected result?
Like in the other browsers, you should be able to scroll as fast or slow as you want and not get blocked.


What happens instead?
You won't be able to scroll at certain moments when you scroll fast and keep the mouse on the same spot. It just blocks you. When you move your mouse when it blocks you, you'll be able to scroll again
