Previously, when hiding the settings overlay, it remains to have a width
of `56` (sidebar width), this is due to the panel content being placed
next to the sidebar, so therefore the content has to move 400
(PANEL_WIDTH) + 56 (sidebar_width) backwards, for the overlay to have a
width of 0 on hide.

Until now, the multiplayer leaderboard would expand during break time.
Now, it respects the user's HUD visibility status (which can be toggled
using Shift+Tab).
