掲示板 Forums - URL Being Constantly Changed When Scrolling Through Forum Posts

I can't seem to reproduce this, but sometime this morning/yesterday evening, I was scrolling down a forum post, then decided to go back to my quiz by pressing the back arrow on msedge/alt+left arrow. I had to do this several times, as the page URL had been modified multiple times when I was scrolling through the post, probably to keep track of the position on the page I had scrolled to.

Perhaps session cookies have already been implemented on most types of forum pages, but there is an exception? Or maybe this morning the change to using cookies to store the position on the page was made?

I'm not entirely sure if using cookies is the best solution in this case, but anything that wouldn't require the URL to be constantly changed would be extremely helpful!
