Shadow endpoints don't invalidate on navigation when component stays mounted

[janosh]

Describe the bug

File [slug].svelte receives data from a get() endpoint in [slug].ts without explicit load function. When the route changes but the new route is also handled by [slug].svelte, the page does not update. Only a full page reload renders fresh data.

Reproduction

Navigate from

https://studenten-bilden-schueler.de/standorte/aachen

via nav to

https://studenten-bilden-schueler.de/standorte/augsburg.

Code at https://github.com/sbsev/svelte-site.

blocking an upgrade

Additional Information

I tried to invalidate the page with

import { afterNavigate, invalidate } from '$app/navigation'

afterNavigate(() => invalidate(slug))

but that has no effect.

This sounds like a duplicate of #3727.

@Conduitry You're right, somehow I didn't find that issue.
