Summary

When I have a scrollable element in ladybird with a visible scrollbar gutter and I scroll the page around it, the scrollbar gutter does not move.

Operating system

Linux

Steps to reproduce

Open the reduced test case
Click the red box's scrollbar so that it keeps showing the scrollbar gutter
Scroll down the entire page
Observe that the gutter stays in place

Expected behavior

The scrollbar gutter should scroll up.

Actual behavior
