System information

Godot v4.1.2.stable - Windows 10.0.19045 - Vulkan (Compatibility) - NVIDIA GeForce GTX 1060 6GB (NVIDIA; 31.0.15.3623) - AMD Ryzen 5 2600X Six-Core Processor (12 Threads)

Issue description

Parent class has a variable with @export
child inherits from that class

when a change is made to the variable i.e changing default value, changing export_range limits, or even deleting the variable all together, these changes do not get reflected in any node with a class that inherits from that parent class

Steps to reproduce

• make a parent class
• give it a class_name
• make a child class which inherits from it
• add an @export variable to the parent class
• create a node for both the parent and child class
• observe that they both have that variable being exported
• modify or delete the variable from the parent class
• it will be updated for the parent class but still display for the child class
