Fragments on query level do not work

[stuebingerb]

According to https://spec.graphql.org/October2021/#example-fdbb7, fragments on Query level should work.

However, the following request

{
    film {
        id
    }
    ...film_title
}

fragment film_title on Query {
    film {
        title
    }
}

fails with

Key Query is missing in the map.
java.util.NoSuchElementException: Key Query is missing in the map.
