@tool and @export_group("", "") after prefixed @export_group do crash editor

[radicalaction]

Godot version

4.0.beta3

System information

Windows 10

Issue description

@tool and little sorting out with @export_group do crash editor. I don't know if I actually made a mistake and this is not how it's supposed to be used but I'm sure that it shouldn't crash the whole engine

Steps to reproduce

1. Attach @tool script onto a scene
2. With scene open, make a prefixed group and close it with @export_group("", "")
3. Make another prefixed group and close it with ("", "") as well.
4. Play around with commenting closing strings and immediately saving them
5. Enjoy your crash
