Windows build doesn't recognize mouse scroll event in ScrollContainer

### Tested versions

- tested in 4.2.1

### System information

Windows 11 - Godot 4.2.1.stable

### Issue description

If I enable touch emulation in the project settings, the _on_scroll_container_scroll_started() and _on_scroll_container_scroll_ended() are correctly fired when I swipe the element.
But when I use the mouse scroll wheel to scroll the element, the element is correctly scrolled, but both events are NOT fired.

### Steps to reproduce

See attached project:
"Scroll started" and "Scroll ended" is displayed when the element is swiped (via mouse touch emulation), but it is not displayed when the scroll wheel is used.

### Minimal reproduction project (MRP)

[Test.zip](https://github.com/godotengine/godot/files/14160196/Test.zip)

Start with the attached Test.zip reproduction and the ScrollContainer handling behind _on_scroll_container_scroll_started() and _on_scroll_container_scroll_ended(). Compare the touch-emulation and mouse-wheel paths on Windows; done means both events are emitted when the element is scrolled with the mouse wheel as well as when it is swiped.
