Bug: Component returning string causes hydration mismatch

[subhero24]

I have a component like this:

function Component() {
    let string = useSuspendingHook()

    return string
}

On the server I render the component with renderToPipeableStream. When hydrating the component I get a Hydration failed because the initial UI does not match what was rendered on the server..

What makes me think this is a bug in react and not my code, is that everything works when I wrap the returned string in a <div> like so:

function Component() {
    let string = useSuspendingHook()

    return <div>{string}</div>
}

Also, would it be possible to have some extra info on the error what the mismatch in hydration actually is?

possibly related to this hydration issue? #24578

Can you please create a minimal reproducing case? Thanks.

Just a reminder we'll need a reproducing case. Otherwise I'll close this.

I failed to create a minimal reproducing case where the problem also happens. Have no idea what makes the situation different with the full application. Will close for now.
