Regression: cannot use QML_ANONYMOUS and QML_UNCREATABLE at the same time

In my app I have

class Foo : public QObject
{
     Q_OBJECT
     QML_ANONYMOUS
     QML_UNCREATABLE("")
}

which compiles fine with Qt 6.2.4 up to 6.4.2

With 6.5.0beta3 however, I get this (output from XCode 14, ios-sim):

/Users/sandman/Qt/6.5.0/ios/include/QtQmlIntegration/qqmlintegration.h:56:16: note: expanded from macro 'QML_UNCREATABLE'
    enum class QmlIsUncreatable {yes = true}; \
               ^
In file included from /Users/sandman/git/brickstore/src/common/script.cpp:9:
/Users/sandman/git/brickstore/src/common/brickstore_wrapper.h:468:5: note: previous definition is here
    QML_ANONYMOUS
    ^ 

As both macros try to create QmlIsUncreatable.

Also the docs for QML_UNCREATABLE (both 6.4 and 6.5) state:

"Some QML types are implicitly uncreatable, in particular types exposed with QML_ANONYMOUS or namespaces exposed with QML_ELEMENT or QML_NAMED_ELEMENT(). For such types, QML_UNCREATABLE() can be used to provide a custom error message."

Which IMHO implies that both can be used at the same time perfectly fine.
