Controller events detected as InputEventKey when Steam is open (due to Steam Input event injection)

[A-Totally-Normal-Name]

Godot version

4.0, 4.0.1

System information

Windows 10

Issue description

If Steam is open on your computer, input from a controller can be incorrectly detected as an InputEventKey. Closing Steam corrects this error.

Controller inputs should never be detected as an InputEventKey: According to the current documentation an InputEventKey is only for keyboard events.

Video demonstration: https://youtu.be/9krmPx9vYoc
Controller used: Dualshock 4

Steps to reproduce

1. Run minimal reproduction project (or a script with the following code):

func _input(event : InputEvent) -> void:
	if event is InputEventKey:
		print ("Keyboard Event Detected")

2. Test if "Keyboard Event Detected" prints on Controller input with Steam open vs. with Steam closed.

This is most likely Steam Input injection doing its thing (so that games that lack controller support can receive keyboard events). Is there any way we could forcibly disable it for Godot by default?

In the meantime, you can disable Steam Input in the Steam settings or in per-game properties.

Quoting @Gramps from #75551 (comment):

The settings you're looking for are in the main Steam settings under Controller > General Controller Settings. If you turn off Configuration Support, you should start getting your inputs back.
