If the browser has 1080 vertical pixels, the scrollbars has max say 1000 possible positions. According to my napkin math* if you scroll over 100 uuids per second it would take up to ~1.7 septillion or ~1 700 000 000 000 000 000 000 000 years to scroll to an uuid of which you know the position if you hit the spot exactly on the scrollbar.

Edit: Use 122 bit instead of 128 due to UUIDv4
