### System information

Windows 10 - Ryzen 7 - 4070ti

### Issue description

When using the threaded resource loader, textures on materials are lost.

This is the scene being loaded in the IDE:

This is the result in runtime:

### Steps to reproduce

Use code such as the following to load a scene:
```
func _load_scene(p_scene_path):
	var new_scene : PackedScene
	if ResourceLoader.has_cached(p_scene_path):
		# Load cached scene
		new_scene = ResourceLoader.load(p_scene_path)
	else:
		# Start the loading in a thread
		ResourceLoader.load_threaded_request(p_scene_path)

		# Loop waiting for the scene to load
		while true:
			var progress := []
			var res := ResourceLoader.load_threaded_get_status(p_scene_path, progress)
			if res != ResourceLoader.THREAD_LOAD_IN_PROGRESS:
				break;

			_progress_bar = progress[0]
			await get_tree().create_timer(0.1).timeout

		# Get the loaded scene
		new_scene = ResourceLoader.load_threaded_get(p_scene_path)
	
	$CanvasLayer.visible = false
	add_child(new_scene.instantiate())
```

Now create a scene to load that has a material with a texture.
