Outer property binding assignment doesn't replace inner binding assignment

 
class MyModuleApi : public QObject
{
    Q_OBJECT
    Q_ENUMS(MyEnum)

public:
    enum Mode { DefaultEnumValue, SomeOtherEnumValue };
};

// MyStyle.qml:
import QtQuick 2.0
import SomeModuleApi 1.0 as Module

QtObject {
    property int foo: Module.DefaultEnumValue
}

// MyWidget.qml:
import QtQuick 2.0

Text {
    property MyStyle style: MyStyle { }

    horizontalAlignment: Text.AlignHCenter
    verticalAlignment: Text.AlignVCenter
}

// TestCase.qml
import QtQuick 2.0
import SomeModuleApi 1.0 as Module

MyWidget {
    width: 300
    height: 300

    style.foo: Module.SomeOtherEnumValue // the value stays at Module.DefaultEnumValue
    text: style.foo
}
