Reactive props?

[zmb3]

Thanks for this library, I've been putting off learning Svelte 5 for lack of a router and this has me back at it.

I'm struggling pass props via the router - it seems I lose reactivity when doing so.

I put together an example on the playground - when I render a component directly and pass props the reactivity works as expected, but when I render a component via the router the props are only evaluated once and the UI doesn't update on future changes.

Any idea what I might be doing wrong here?
