get_next_dialogue_line is not available when run in editor

[stephanbogner]

First of all: This project is so great! It's so much fun to work with, because it's so easy to adjust the whole appearance and behaviour to my needs ❤️

Describe the bug

1. When I run await dialog_resource.get_next_dialogue_line("") in the editor using @tool ...
2. ... I get the following error: res://main.gd:8 - Invalid call. Nonexistent function 'get_next_dialogue_line' in base 'Resource (DialogueResource)'.
3. It works perfectly fine once the game is started

Context

I want to show the content of some on-screen speech bubbles already while I am editing.

Affected version

• Dialogue Manager version: 2.33.0
• Godot version: v4.2.1.stable.official [b09f793f5]

To Reproduce

1. Create a new dialog
2. Attach the following script to a node

@tool
extends Node2D

@export var dialog_resource:DialogueResource

func _ready():
	if dialog_resource:
		print(await dialog_resource.get_next_dialogue_line(""))

3. Choose your dialog as the dialog_resource
4. Close and reopen the scene tab to trigger the error

Expected behavior

That get_next_dialogue_line() also works inside the editor
