It's definitely better, but I'm still noticing an issue here with this PR installed:

https://stackblitz.com/edit/sveltejs-kit-template-default-ndhoiwgy?file=package.json,src%2Froutes%2F[slug]%2F%2Bpage.svelte

Yes, I noticed that too. Even without a top-level await, there’s still a weird bug: if you have two links to the same slug, hover over both, and then click one, the page params ends up empty.

I also noticed that if you don’t have a +layout, the page doesn’t render at all after hovering both links and then clicking one. Example here: https://stackblitz.com/edit/sveltejs-kit-template-default-4l8r8anj?file=src%2Froutes%2F%5Bslug%5D%2F%2Bpage.svelte
