So recently we landed this animation for two finger swipe that slides the current page off the side of the screen. I find that this often breaks with in page "#" links (like on DXR files or jorendorff's html version of the current ES6 draft) and I end up on an empty white page. With pushState (such as on github, navigating between directories of some repo) sometimes it works, sometimes it doesn't. I have seen the previous page (or a screenshot of it?) that I can't interact with or scroll around until I refresh. I have also seen the blank page.
