Horizontal scroll bar is not available

[MaxJPRey]

The horizontal scroll bar is not available unless you scroll down to the bottom.
To reproduce the issue, you can open this link.

If you scroll down, you will see the horizontal scroll bar showing up again.

With the new collapse navigation, we might not need this horizontal scroll bar as much as we used to.
This might already be fixed. In that case, feel free to close it.
