Object::emit_signal needs to check for @tool

System information

Issue description

here an error is generated like this example

This is solved by adding the @tool keyword is it possible to check if the Editor is running this line?

If so error text may suggest the tool keyword.

Steps to reproduce

tool
extends EditorPlugin

var dialogue_editor_window_path = "res://addons/DialogueEditor/DialogueEditorWindow.tscn"

func _enter_tree():
    InputMap.add_action("open_dialogue_editor")
    var new_input_event = InputEventKey.new()
    new_input_event.set_scancode(KEY_Q)
    InputMap.action_add_event("open_dialogue_editor", new_input_event)

func _exit_tree():
    InputMap.erase_action("open_dialogue_editor")

func _input(event):
    if event.is_action_pressed("open_dialogue_editor"):
        var dialogue_editor_window = load(dialogue_editor_window_path).instance()
        dialogue_editor_window.get_node("Button").connect("pressed",dialogue_editor_window,"_on_button_pressed")
        add_child(dialogue_editor_window)

extends Panel

func _on_button_pressed():
    queue_free()

We could make a list of classes that should be used with @tool and generate a warning if it is missing. I had this thought while working on #78178.

Was this resolved by #94511?

Looks like it. Then we should close this as a duplicate of #36592. I misunderstood this issue last time.
