Compiler error when using `enum` subclasses of Object as properties

When I create an enum type and use the glib::Enum derive proc-macro, I get a compiler error from within the glib::Properties derive proc-macro when trying to use my enum as a property. The compiler error:

error[E0061]: this function takes 2 arguments but 1 argument was supplied
  --> src/main.rs:28:5
   |
25 | #[derive(glib::Properties)]
   |          ---------------- an argument of type `TestType` is missing
...
28 |     #[property(get, set)]
   |     ^^^^^^^^^^^^^^^^^^^^^

In the code below, if I change the_test_type to be a RefCell<i32> or a RefCell<TestTypeStruct>, it works:

use gtk4::prelude::*;
use gtk4::subclass::prelude::*;
use std::cell::RefCell;

use gtk4::glib::{
    self,
    subclass::{object::ObjectImpl, types::ObjectSubclass},
};

// Does NOT work when `the_test_type` is RefCell<TestType>
#[derive(Clone, Copy, glib::Enum)]
#[enum_type(name = "TestType")]
enum TestType {
    One,
    Two,
}

// Works when `the_test_type` is RefCell<TestTypeStruct>
#[derive(Clone, Copy, glib::Boxed)]
#[boxed_type(name = "TestTypeStruct")]
pub struct TestTypeStruct {
    value: i32,
}

#[derive(glib::Properties)]
#[properties(wrapper_type = wrapper::Test)]
pub struct Test {
    #[property(get, set)]
    pub the_test_type: RefCell<TestType>,
}

impl Default for Test {
    fn default() -> Self {
        Test {
            the_test_type: RefCell::new(TestType::One),
        }
    }
}

#[glib::derived_properties]
impl ObjectImpl for Test {}

#[glib::object_subclass]
impl ObjectSubclass for Test {
    const NAME: &'static str = "Test";
    type Type = wrapper::Test;
    type ParentType = glib::Object;
}

mod wrapper {
    use gtk4::glib;

    glib::wrapper! {
        pub struct Test(ObjectSubclass<super::Test>);
    }
}

I took a look through the output of cargo expand, but I couldn't determine the function that the error is referring to. Thank you for your time!
