Assertion in QQmlPropertyData::setOverrideIndex

When building Qt in debug mode my application runs into the following assertion:

ASSERT: "idx != m_coreIndex" in file qtbase/include/QtQml/6.4.1/QtQml/private/../../../../../../qtdeclarative/src/qml/qml/qqmlpropertydata_p.h, line 243

The assertion is related to having READ/WRITE accessors of a property also being defined as Q_INVOKABLE.

Of course this does not make much sense and can be solved easily by simply removing the Q_INVOKABLE keyword. However it took me some time to find the reason for the assertion and I thought it is worth to at least report it.

class Gradient
{{{}}
    Q_GADGET

    Q_PROPERTY( QVector< Stop > stops READ stops WRITE setStops )

  public:

     Q_INVOKABLE void setStops( const QVector< Stop >& );
     Q_INVOKABLE const QVector< Stop >& stops() const;

};
