Issue with handling 404 for statically prerendered dynamic routes (SSG)

[jakubszpil]

Hi, is this an issue or WAD functionality in terms of following error?

Error: No result found for routeId "article-details"

Routes configuration:

/ -> routes/home
/blog -> routes/article-list
/blog/:slug -> routes/article-details
/search -> routes/search
/* -> routes/not-found

Dynamically generated blog routes:

/blog/example-1
/blog/example-2

loader from article-details

export async function loader({ params: { slug } }: LoaderFunctionArgs) {
  const article = await ArticleService.findUnique(slug);

  if (!article) {
    throw new Response(null, {
      status: 404,
      statusText: "Not found",
    });
  }

  return article;
}

Entering invalid route /xyz works fine -> not-found route shows up
Entering invalid route /blog/test does not work correctly -> error thrown by unwrapSingleFetchResult shows up in root ErrorBoundary
