Describe the bug

In some cases clicking a link updates the browser's URL, however the page and the components do not change. This appears to be something related to nested layouts.

Everything starts working correctly if I remove the data-sveltekit-preload-data="hover" attribute on the body tag.

I'm wondering if there's something happening to navigation state here where SvelteKit thinks it's navigated and it actually hasn't. I don't know if this has already been tracked in another issue

Reproduction

An example repository is available here: https://github.com/gordysc/svelte-navigation-bug-example

If I remove data-sveltekit-preload-data="hover" from the body tag everything works.

Severity

Serious, but I can work around it

Additional Information

We definitely want to keep the preload attribute but if we have to move off it for now so the correct behavior works that's okay (although not ideal). If we hav to move off of remote functions that's also unfortunate, but managable.
