In Chrome, the URLs in comment 6 load just fine, but I can trigger the navigation from the first URL to the second URL if I scroll down all the way (and dismiss a modal popup that appears at one point). It looks like maybe there's an intersection observer that navigates (maybe just using `pushState` or similar) when you scroll down far enough. I wonder if that intersection observer is being prematurely triggered in Firefox for some reason.
