+error.svelte and "walk up the tree"

[bjon]

Anyone got this to work?

From https://kit.svelte.dev/docs/routing#error
SvelteKit will 'walk up the tree' looking for the closest error boundary — if the file above didn't exist it would try src/routes/blog/+error.svelte and src/routes/+error.svelte before rendering the default error page.

If I create /blog/+error.svelte, and forces an error, it never renders. Only /+error.svelte gets rendered.
