Double scrollbar on crossuniverse.net

[Psychpsyo]

Summary

When I open crossuniverse.net in Ladybird, sometimes the page has two scrollbars on the right side.
They show on top of one another and one is only movable by scrolling, while the other only reacts to dragging it with the mouse.

Operating system

Linux

Steps to reproduce

1. Go to crossuniverse.net
2. Scroll to see if there is two scrollbars.
3. If there is not, reload the page and go to step 2 until there is.

Expected behavior

There should only be one scrollbar.

Actual behavior

There is two scrollbars
The devtools, (if you have #2443 applied), only show one scrollable element though.
