Describe the bug

The focus_follows_cursor option only works with an external mouse. If moving the cursor by using a touchpad (i.e. a built-in laptop touchpad), this option doesn't work: despite moving the cursor over a different window, the focus doesn't change. If you do the same thing by using a mouse, then the option works correctly and cursor changes window focus.

For clarity, I'm using a Huawei Matebook D15 AMD running Windows 11.

Reproduction

1. Enable the focus_follows_cursor option.
2. Try moving the mouse cursor to another window by using a touchpad.
3. Observe focus staying on the same window, not changing when hovering the cursor over another window.
