Depends.profiles does not work when dependency has an aggregator

Project {
    Profile {
        name: "profile1"
    }
    Profile {
        name: "profile2"
    }

    Product {
        name: "dep"
        qbs.profiles: ["profile1", "profile2"]
        aggregate: true
        Depends { name: "cpp" }

        Export {
            Depends { name: "cpp" }
            cpp.defines: product.qbs.profile
        }
    }
    Product {
        name: "main"
        Depends { name: "dep"; profiles: ["profile1"]; }
        Depends { name: "cpp" }
        property string whatstheprofile: {
            console.info(cpp.defines);
        }
    }
}
