Deno FileServer Tutorial Incorrect?

I had a look at the official fileserver tutorial (https://docs.deno.com/runtime/tutorials/file_server/) and saw the below

try {
  const file = await Deno.open("." + filepath, { read: true });
  return new Response(file.readable);
} catch {
  return new Response("404 Not Found", { status: 404 });
}

try {
  const file = await Deno.open("." + filepath, { read: true });
  return new Response(file.readable);
} catch {
  return new Response("404 Not Found", { status: 404 });
}

However, if my understanding is correct, the file resource is leaked because it's never closed but if opened with using it might be closed before the Response finished streaming. Am I missing something and the example is actually correct or is this bad code?
