Matching a Partial object does not work when constructing the object using an object literal when using generics in Typescript

Question

When using the following construct Typescript fails to infer the correct type and match it with a partial of the same object. I assume this is not a bug and I am missing something. Can anybody tell me what I am missing?

class Repository<DTO extends {
    id: string
}> {
    findOne(what: Partial<DTO>) {
    }

    get(id: DTO["id"]) {
        this.findOne({ id }); // TS2345: Argument of type '{ id: DTO["id"]; }' is not assignable to parameter of type 'Partial '.
        this.findOne({ id } as Partial<DTO>); // manual casting works
    }
}

If anybody has a better suggestion for the title please go ahead, this is almost impossible to search.
