### Issue description

```
        virtual Ref<Script> get_script() const override {
                if (native_info->get_script_func) {
                        GDExtensionObjectPtr script = native_info->get_script_func(instance);
                        return Ref<Script>(reinterpret_cast<Script *>(script));
                }
                return Ref<Script>();
```
Is not creating a functional reference.

GDExtensionObjectPtr is a part of gdextension_interface and is a void pointer to pas data pointers between GDExtesion and Godot Core.

In the images below you are able to see that the extension `reinterpret_cast `works fine.
And that the pointer is passed to core.
However at core `Ref<Script> script_test` stays a NULL value

I was hoping this would be solved by solving [cpp 1119](https://github.com/godotengine/godot-cpp/issues/1119)



### Steps to reproduce

Create a custom script instance and create it using `internal::gdextension_interface_script_instance_create` and a `GDExtensionScriptInstanceInfo` that only implements `get_property_list_func` and `get_script_func`.

### Minimal reproduction project

Difficult to create a minimal project.
Mostly looking for advice on what to test to find the actual source problem
