Issue:
`--svelte-bracket-new-line true` not working correctly (e.g. button and span)
`src/test.svelte`:
```svelte
<button class="bg-green-500  text-gray-100 hover:bg-green-400 flex items-center px-4 py-2 border border-l-0 rounded-r"> Copy </button>
<div class="bg-green-500  text-gray-100 hover:bg-green-400 flex items-center px-4 py-2 border border-l-0 rounded-r"> Copy </div>

<p class="bg-green-500  text-gray-100 hover:bg-green-400 flex items-center px-4 py-2 border border-l-0 rounded-r"> Copy </p>
```
