Describe the bug

reproduction:
https://www.sveltelab.dev/ir0u7dml3b168h6?files=.%2Fsrc%2Froutes%2Fsuccess%2F%2Bpage.svelte

1. Click "go to page"
2. Submit form
3. The success message renders. Click "Go to target page".
4. ERROR: The "No success state" from the previous page is rendered on the target page. It keeps persisting even after subsequent navigation to the home page.

This only happens if the transition is "global", and using the experimental async compiler option.

This started happening after I upgraded from svelte@5.26.3 -> svelte@5.37.3 and @sveltejs/kit@2.17.2 -> 2.27.0
