StackView (Controls 2.0) doesn't work with http url on first try

Documentation clearly states that .push can receive a (network) url
http://doc.qt.io/qt-5/qml-qtquick-controls2-stackview.html#push-method

However using network url (on first try):

StackView {
    Component.onCompleted: push("http://127.0.0.1:8080/test.qml")
}

produces

Component is not ready

Which is obviously because component is not yet loaded and created.

As a workaround one would have to create this component dynamically and wait for ready status, then provide that to StackView
