cursor not changed when hovering over the difficulty icon but difficult button yeah

OS: Arch Linux

Steps to reproduce:
1. Hover over the difficulty icon in the game menu

1. Observe cursor behavior

Expected result:
Cursor should change to indicate the icon is not selectable (e.g., show a disabled or "not allowed" cursor) when hovering over the difficulty icon.

Actual result:
Cursor does not change when hovering over the difficulty icon, but changes over the difficult button.
