Describe the problem

I am running into an issue, where if I use 'data' => Inertia::defer(fn() => $data), it gets lazy loaded fine. But if I then visit some other site, and click the browsers "back" button, the deffered data wont load.

It works if i use 'data' => Inertia::otpional(fn() => $data)

and

    useEffect(() => {
        router.reload(["data"]);
    }, []);

Is anyone else getting this and is this expected?

Steps to reproduce

1. Pass data with defer 'data' => Inertia::defer(fn() => $data)
2. Open page (loads fine)
3. Open any other page, like google.com
4. Press browser back, deferred props wont load
