[REG] Non-Singlebit Q_FLAGS not exposed correctly in property declarations

Actually noticed this while writing another bugreport:

I have a simple use case for flags in qml:

class ControlFlags : public QObject 
{
    Q_OBJECT
    QML_ELEMENT
    QML_UNCREATABLE("Flag Container Class")

public:
    ControlFlags() = delete;

    enum Option {       
        ControlA = 0x1,
        ControlB = 0x2,       
        Both = ControlA | ControlB   
    }

    Q_DECLARE_FLAGS(Options, Option)
    Q_FLAG(Option)
};

Q_DECLARE_OPERATORS_FOR_FLAGS(ControlFlags::Options)

using this in qml is fine up to the point, where we use Both. Both is available in qt creator and has meta information generated, but accessing it always gives -1.

So in qml, writing ControlFlags.ControlA | ControlFlags.ControlB != ControlFlags.Both.

In my use case, I have a component, which has flags as required property, when I use it like this:

Item {
    requiredFlags: ControlFlags.Both 
}

I get an invalid configuration back
