Scroll the whole page to the bottom.
Place your mouse cursor just below the large scroll frame.

I can't reproduce either on Windows 11 or on Mac.

Maybe the site has changed?

Timothy, can you explain the exact position where should the mouse cursor be aligned? I guess it's on the header "Rank # Name" etc.?

Sorry,

"Place your mouse cursor just before the large scroll frame."

should be

"Place your mouse cursor just below the large scroll frame."

I edited the first comment to fix that.

With those steps I just reproduced the problem now.

Thanks Timothy. I finally can reproduce on Mac. For some reasons I can't see the issue on my Windows laptop, but I think there should also be reproducible.

Anyway, this looks similar to bug 1857671, but non-iframe version? Blocking overscroll-post.
