QGraphicsSimpleTextItem says it is a QGraphicsItem when printed with qDebug()

If I type

QGraphicsSimpleTextItem *test_simple_text = new QGraphicsSimpleTextItem(QStringLiteral("test simple text")); qDebug() << "*** QGraphicsSimpleTextItem:" << test_simple_text;

it shows

*** QGraphicsSimpleTextItem: QGraphicsItem(0x562fda1f7250, pos=0,0)

I would expect it to display

** *QGraphicsSimpleTextItem: QGraphicsSimpleTextItem(0x562fda1f7250, pos=0,0, flags=(ItemUsesExtendedStyleOption))

Thats's said, it works as expected with QGraphicsTextItem.

QGraphicsTextItem *test_text = new QGraphicsTextItem("test text"); qDebug() << "*** QGraphicsTextItem:" << test_text;

it displays

*** QGraphicsTextItem: QGraphicsTextItem(0x562fda57e950, pos=0,0, flags=(ItemUsesExtendedStyleOption))
