Refactor one folder is making a working Node to be detected as cyclic dependency

[immccc]

Godot version:
3.2.3.Stable

OS/device including version:
Windows 10 Home.

Issue description:
I have two nodes to be defined by a plugin. One instances the other internally, but not vice versa in any way (neither directly nor through a chain of classes)

Both nodes compile and behave as expected. But after refactoring the instanced one to the same folder as its consumer, I get (script error or cyclic dependency) error.

Steps to reproduce:
Given the following source tree:

• Addons
• • plugin_name
• • • plugin.gd
• • • controller
• • • • controller.gd
• • • cursor
• • • • cursor.gd

Refactor to:

• Addons
• • plugin_name
• • • plugin.gd
• • • controller
• • • • controller.gd
• • • • cursor
• • • • • cursor.gd

Expected:
Plugin behaves the same

Actual:
An error (script error or cyclic dependency) is shown where Cursoris instanced.

Minimal reproduction project:

Inside plugin.gd, instantiation to custom types are done like:

enum CustomType {
    CONTROLLER,
    CURSOR
}


const CustomTypes: Array = [
    CustomType.CONTROLLER,
    CustomType.CURSOR
]

const NamesForCustomType: Dictionary = {
    CustomType.CONTROLLER: "Controller",
    CustomType.CURSOR: "Cursor"
}

const ParentTypesPerCustomType: Dictionary = {
    CustomType.CURSOR: "AnimatedSprite",
    CustomType.CONTROLLER: "Node"
 
 const SourceForCustomType: Dictionary = {
    CustomType.CURSOR: Cursor,
    CustomType.CONTROLLER: Controller
}

const IconPerCustomType: Dictionary = {
    CustomType.CURSOR: "res://addons/adventurator/cursor/cursor.png",
    CustomType.CONTROLLER: "res://addons/adventurator/controller/adventure_controller.png"
}

func _add_custom_types():

    for custom_type in CustomTypes:
        add_custom_type(
            NamesForCustomType[custom_type],
            ParentTypesPerCustomType[custom_type],
            SourceForCustomType[custom_type],
            load(IconPerCustomType[custom_type]))
        print_debug("Added custom type ", NamesForCustomType[custom_type])

 

Nothing fancy in cursor.gd:

tool
class_name Cursor
extends AnimatedSprite

#...

But In controller.gd, instantiation is made like:

tool
class_name Controller
extends Node

var cursor: Cursor = Cursor.new() # <--- This is the line where the issue is shown


func _enter_tree() -> void:
    GlobalRepository.add_controller(self)    # Silly autoloaded plugin for some kind of context for dependency injection

func _ready() -> void:
    
    add_child(cursor)

An error (script error or cyclic dependency) is shown where Cursoris instanced.

Is this error still visible after restarting the editor?

Unfortunately yes. This is only solved when I move back cursor folder to its old position, as sibling of "controller" instead of child.
