$top/$skip not working within $expand

[blitzmann]

{{base_url}}/api/authors?$expand=posts($orderby=id desc;$top=1)&$filter=id eq 5

This returns

[
    {
        "id": 5,
        "name": "Emmanuel Salinas",
        "posts": [
            {
                "id": 10,
                "title": "Cursus Ltd",
                "text": "ac mattis ornare, lectus ante dictum mi, ac mattis velit"
            },
            {
                "id": 5,
                "title": "Habitant Morbi Tristique Corp.",
                "text": "Suspendisse"
            }
        ]
    }
]

I would expect it to return (taking the first value that is returned)

[
    {
        "id": 5,
        "name": "Emmanuel Salinas",
        "posts": [
            {
                "id": 10,
                "title": "Cursus Ltd",
                "text": "ac mattis ornare, lectus ante dictum mi, ac mattis velit"
            }
        ]
    }
]

Granted, this might be a limitation in TypeORM. If you're trying to page records within a join, I believed that would require a subquery instead of just joins. I'm going to poke around and see what I find out.
