Adding/removing base class export does not properly update inspector for inherited scripts

Godot version

System information

Godot v4.1.1.stable - Windows 10.0.22621 - Vulkan (Forward+) - dedicated AMD Radeon RX 6700 XT (Advanced Micro Devices, Inc.; 27.20.21034.37) - AMD Ryzen 7 5700X 8-Core Processor (16 Threads)

Issue description

When you have a script inheriting a script, adding or removing exports to/from the base script does not cause the inspector to update, leaving in stale values or not showing new values. Adding or removing exports from/to the inherited script works fine.

Before

After

Steps to reproduce

Base class

class_name BaseClass
extends Node3D


@export var base_a := 1
@export var base_b := 2

Inherited script (attach it to a node)

extends BaseClass


@export var not_inherited := 1234

You can trigger the issue by adding or removing exports from/to the base class.

Huh, it's weird how this has not been triaged yet. Seems to be happening to other issues, too.
