Issue description

If you use a Scene Collection in a TileMap, when you add a new cell to a TileMap, all tiles in a layer are re-created.

Scene Tile:

Code:

extends Node2D

func _ready():
	randomize()
	var r = randf()
	var g = randf()
	var b = randf()
	$Label.text = name
	$Label2.text = str(get_instance_id())
	$Sprite2D.modulate = Color(r, g, b)

Steps to reproduce

1. Create a Scene Collection in a TileSet and add a scene to it.
2. Set few cells in a TileSet at runtime.
3. All nodes in a layer will re-created every time you set a new cell.
