Weird scrolling behavior here when navigating threads.

[Unknown Zombie]

It's really annoying trying to read threads with multiple pages here.

 

I begin scrolling down a thread, reading the posts, and at the bottom of the page I click the "Next" button to move on to the next page. The site scrolls up, loads the next page, and once the page is loaded it jumps back down to the bottom of the page. So, then, to actually start reading this page of posts I have to manually scroll back to the top. Rinse and repeat every time I move to the next page of a thread.

 

Why does it do this?
