Issue description

I've a custom class in addon folder. It has a func named with fetch_class_name. The auto-complete for this func not show up. After I close the IDE and reopen then it works as expected.

Steps to reproduce

Create gd script in res://addons/fsm/state.gd

extends Node
class_name State
@icon("res://addons/fsm/state_logo.svg")

var state_machine: StateMachine
var target

static func fetch_class_name() -> String:
	return "State"
	

func enter() -> void:
	print(666)


func update():
	pass


func exit():
	pass

In another script res://addons/fsm/state_machine.gd

extends Node
class_name StateMachine
@icon("res://addons/fsm/state_machine_logo.svg")

@export var init_state = NodePath()
@onready var _target_node: Node = get_parent() as Node
@onready var _states: Array[State] = []


var cur_state: State 
var _states_map: Dictionary = {}

func _ready():
	for child in get_children():
		if child.get_class() == State.fetch_class_name():
			_states.append(child)
	for state in _states:
		state.target = get_parent()
		state.state_machine = self
		_states_map[state.name] = state
	cur_state = get_node(init_state) as State
	cur_state.enter()


func _process(delta):
	pass

The auto completion doesn't work for State.fetch_class_name() and cur_state.enter()

Then close the IDE and reopen it.

It will work as expected

Then close the IDE and reopen it.

To clarify, are you using the built-in script editor or an external editor?

[nofacer]

@Calinou I'm using built-in script editor.

Happens on v4.2.beta5 as well, using built-in editor.

Still happening on v4.2.1, this is a bit annoying.

Thanks for the report! Consolidating in #78074, as this is due to the same cause (cyclic reference).
