Tested versions

• Reproducible in: 4.3.stable, 4.3.beta1
• Not reproducible in:
  • 4.3.dev6, 4.2.1 (can't really test it because Input.parse_input_event was broken, see #85984)
  • 4.1.3 (working as expected)

System information

Godot v4.3.stable - macOS 14.6.0 - Vulkan (Forward+) - integrated Apple M1 Pro - Apple M1 Pro (10 Threads)

Issue description

When using Input.parse_input_event to trigger an action, it releases all other pressed actions.

This issue occurs since Input.parse_input_event got fixed by #86010, but I'm not sure if it is the root cause or not.

Steps to reproduce

func _ready():
    await get_tree().create_timer(1).timeout
    Input.action_press("ui_a")
    Input.action_press("ui_b")
    Input.action_press("ui_c")
    await get_tree().create_timer(1).timeout
    var event = InputEventAction.new()
    event.action = "ui_d"
    event.pressed = true
    Input.parse_input_event(event)

In this example, we press three actions using Input.action_press, and then use Input.parse_input_event to press the fourth action. As the video shows, it released all other actions.

Using the MRP below, you can also use the keyboard to test, the "a" and "b" keys using Input.action_press, "c" and "d" keys using Input.parse_input_event.
