[Reg 5.15 -> 6.1] Not possible to use Loader inside inline component

component MyComponent : Loader {
    sourceComponent: Item {}
}

 Cannot assign object of type "Item" to property of type "QQmlComponent*" as the former is neither the same as the latter nor a sub-class of it.

component MyComponent : Item {
    Loader {
        sourceComponent: Item {}
    }
}

Component elements may not contain properties other than id
