Simulating keypresses 4.1->4.2 regression

[Dan2552]

Tested versions

• Reproducable in 4.2, 4.2.1-rc1
• Not reproducable in 4.1.3

System information

macOS

Issue description

Input.parse_input_event and/or Input.flush_buffered_events not working as expected (or at least as previous)

Steps to reproduce

Create empty project, 2D scene, drag godot icon into scene to act as a Sprite2D node and add script:

extends Sprite2D

func _ready():
	setup_inputmap()
	press_left(true)

func _process(delta):
	var velocity = Vector2()

	if Input.is_action_pressed("left"):
		velocity.x -= 1

	velocity = velocity.normalized() * 200
	position += velocity * delta

func press_left(pressed: bool):
	var input_event = InputEventAction.new()
	input_event.action = "left"
	input_event.pressed = pressed
	Input.parse_input_event(input_event)
	Input.flush_buffered_events()

func setup_inputmap():
	var action_name = "left"
	InputMap.add_action(action_name)
	var event_key = InputEventKey.new()
	event_key.keycode = KEY_A
	InputMap.action_add_event(action_name, event_key)

In 4.1 the sprite will move left
In 4.2 the sprite will not move

On Mac, and can reproduce with Godot 4.2.1, 4.2.2.rc2, and 4.3.dev5.
