Autocomplete incorrectly infers Autoload property types for custom class types

[Haydoggo]

Godot version

v4.0.rc1.official [8843d9a]

System information

Windows 10

Issue description

When referencing an Autoload's property, if that property is a custom class, autocomplete will incorrectly infer the type of that property as Object.

In Godot 3.5.1, this issue is not present and autocomplete acts as expected.

Steps to reproduce

Given the following 3 scripts:

# custom_class.gd
class_name CustomClass extends Node

var mesh : Mesh

↓ Add this one to Autoloads in project settings

# autoload.gd
extends Node

var mesh : Mesh
var custom_class : CustomClass

# main.gd
extends Node

func _ready():
	CustomClass.new().mesh # autocomplete works as expected
	Autoload.mesh # autocomplete works as expected
	Autoload.custom_class.mesh # autocomplete acts as though custom_class were of type Object

(At this point I restart the editor because there seem to be some issues with autocomplete and fresh autoloads/custom classes anyway)

In the final line of main.gd, after typing Autoload.custom_class., autocomplete suggests only members of Object (eg. free(), add_user_signal(), etc.), and does not suggest any members of CustomClass nor of its base type Node

I can confirm this still happens with Godot v4.0.stable.official [92bee43] on linux.

This is also similar to a problem I have where an autoload singleton has some onready vars to reference its children and, when I access them outside of the singleton using its global variable, Godot only autocompletes their base class methods and not the ones I wrote in the child script, even if everything is statically typed.
