Issue description

I has a root scene contains a scene2 in the node tree, and if now I use preload() function in other .gd files, will cause ' possible cyclic resource inclusion' error.

Steps to reproduce

if you use my reproduction project directly:
(on start, output will get a error, scene1.gd will auto disattach from scene1.tscn)

1. attach scene1.gd on scene1.tscn
2. run the scene2, will show errors in output

start from a new project:

1. create two scenes: scene1.tscn, a scene2.tscn
2. scene2.tscn instantiates a child from scene1.tsn
3. scene1.tscn add a script, add write:

extends Node2D
class_name Scene1

const scene1 := preload("res://Scene1.tscn")

func Create() -> Scene1:
	# scene1 will be null
	return scene1.instantiate() as Scene1

6. run the scene2 or restart the editor, will show errors

Use load() instead of preload(), as cyclic references are not supported with preload().

[AThousandShips]

cyclic references are not supported with preload().

Should probably be documented
