Describe the bug
(group) seems to be optional in resolve() as patched in https://github.com/sveltejs/kit/commit/1cd93cd7b29fde3c8d28a920bc9d02292ce8bbc7
However, the patch is incomplete and should be reverted.
<script>
import { resolve } from '$app/paths';
</script>
<!-- 1: Works as expected. -->
<a href={resolve('/(group)/[slug]', { slug: 'hello' })}>label</a>
<!-- 2: Works as expected. -->
<!-- Expected 2 arguments, but got 1. js(2554) -->
<a href={resolve('/(group)/[slug]')}>label</a>
<!-- 3: Shouldn't this error? -->
<a href={resolve('/[slug]')}>label</a>
<!-- 4: This shows an incorrect error -->
<!-- Expected 1 arguments, but got 2. js(2554) -->
<a href={resolve('/[slug]', { slug: 'hello' })}>label</a>More context:
