Async SSR and client-side navigation causes elements to persist

[teemingc]

Describe the bug

It seems like an async component that is SSR-ed causes all the elements below it to persist after client-side navigation. Not sure if this is an issue with Svelte or SvelteKit.

Reproduction

https://stackblitz.com/edit/sveltejs-kit-template-default-yjjdovwo?file=src%2Froutes%2F%2Bpage.svelte

1. Run npm run build && npm run preview
2. Click on the navigation link to /about
3. Observe that the paragraph from the home page persists in the new page

This might be a webkit issue because it occurs after build on Safari iOS and MacOS. Haven’t tried Chrome.

EDIT: It still happens on Chrome MacOS
