Q_GADGET properties don't get boilerplate "This property holds" intro

QObject properties, such as QObject::objectName, are documented with

/*!
    \property QObject::objectName

    \brief the name of this object

which generates documentation that states

This property holds the name of this object

The same input for QEvent::accepted:

/*!
    \property  QEvent::accepted
    the accept flag of the event object

result in just

the accept flag of the event object

It would seem that qdoc's XmlGenerator::rewritePropertyBrief is not used for Q_GADGET properties.
