InputEventMouseMotion does not fire with captured mouse mode

[RedMser]

Tested versions

• Reproducible in today's master: 0e50807
• Not reproducible in Godot_v4.3-dev5

System information

Godot v4.3.dev (0e50807) - Windows 10.0.19044 - GLES3 (Compatibility) - NVIDIA GeForce RTX 2080 (NVIDIA; 31.0.15.5186) - Intel(R) Core(TM) i7-8700K CPU @ 3.70GHz (12 Threads)

Issue description

When using Input.mouse_mode = Input.MOUSE_MODE_CAPTURED, no InputEventMouseMotion events fire in _input or _unhandled_input. I believe this to be a regression from previous versions, as I don't see it documented anywhere.

Steps to reproduce

• Create a Node + Script:

extends Node

func _ready() -> void:
	# this breaks mouse motion events - change mouse mode to have InputEventMouseMotion print
	Input.mouse_mode = Input.MOUSE_MODE_CAPTURED

func _input(event: InputEvent) -> void:
	print(event)

func _unhandled_input(event: InputEvent) -> void:
	print(event)
	
	# allow quitting via escape
	if event.is_action_pressed("ui_cancel"):
		get_tree().quit()

• Run project and try moving the mouse
• There is no prints for mouse movement
