I don't think I did anything - I hardly interacted with the page at all, except from skipping a Soundcloud track once and possibly resizing the page.

At one point, it switched from "world view" to "US continental view" to show a hyperlapse from Miami, and then got stuck there in perpetuity.

Edit — or maybe I had a blackout and this is resize-related as well. It would make sense if I shrank the window, so half of the map got stuck outside the window. Never mind then :)
