I've been testing a flow where I have an SSR page that includes a client component. This client component simply renders an <h1> with the result of a function call — and that function just returns a string.

To my surprise, when I change the function's return value, HMR does kick in, but the client component doesn't re-render to reflect the updated result. I was expecting it to behave similarly to server components, where changing an imported function causes any dependent component to re-render.

I’ve put together a minimal reproduction here:

Before opening a bug report, I just want to make sure I’m not misunderstanding something or doing it wrong. Any insights are appreciated!
