In Windows 11 there is an option in **Settings -> Bluetooth & devices -> Mouse** called **Scroll inactive windows when hovering over them**, which IIRC is enabled by default. Windows 10 has something similar. With it enabled you can e.g. change the selected item in an unfocused combo box by hovering over it and scrolling. It is also mentioned here: https://devblogs.microsoft.com/oldnewthing/20160420-00/?p=93325
