Godot 4 class_name autocomplete not consistently working when attaching to parent class node despite using static type declarations and only works if "as" keyword is used

[mmmmmmmmmmmmmmmmmmmdonuts]

Godot version

4.1.1

System information

windows 11

Issue description

When registering a type with class_name and using that class name to declare a variable in code only, autocomplete works as expected anywhere in other nodes/scenes. However, if making a custom scene node that extends a script with the class_name, if that custom scene is instantiated in a different scene, even if the type is specified, it only shows the parent node's functions and not any of the extended functionality. I have made a basic project showing the issue

Steps to reproduce

I have made a very simple project showing the issue. https://github.com/mmmmmmmmmmmmmmmmmmmdonuts/godot_4_autocomplete_issue essentially, the extended Node scene will only show the custom function when both the type is specified as well as the type afterwards following "as"
e.g. @onready var my_class_4: MyClass = $MyClass4 as MyClass

I can confirm this. It completely ignores the type unless there is an "as" keyword.

Basic health component class:

extends Node
class_name HealthComponent

signal died

@export var max_health: float = 10
var current_health

func _ready():
	current_health = max_health

func damage(damage_amount: float):
	current_health = max(current_health - damage_amount, 0)
	Callable(check_death).call_deferred()

func check_death():
	if current_health == 0:
		died.emit()
		owner.queue_free()

and using it in another script like this:

1. @onready var health_component: HealthComponent = $HealthComponent (this does NOT offer autocomplete)
2. @onready var health_component: HealthComponent = $HealthComponent as HealthComponent (this offers autocomplete)
3. @onready var health_component = $HealthComponent as HealthComponent (this offers autocomplete)

using export like this:

@export var health_component: HealthComponent does offer autocomplete.

but option 1 should offer autocomplete.

PS: Code blocks should use triple backticks like this (with an optional language name for syntax highlighting):

```gdscript
code here
```

I edited your post accordingly, but remember to do this in the future 🙂

Isn't this related to an older issue about editor suggestions/autocompletion not being consistent?

Edit: Here, found the issue #42005

ooh! thank you very much!

I really hope this gets some attention to get fixed ><

I have nothing to add, other than that this just hit me and cost a little bit of time. Using Godot 4.1.1
