"""PYSIDE-3069: Test that the conversion of an element of a list
QGraphicsItem* to QGraphicsProxyWidget* (inheriting QObject/QGraphicsItem)
works correctly without crash.
For this, we need a QGraphicsProxyWidget for which no wrapper exists,
created in C++. So, we populate a combo, add it to the scene and show its
popup, which creates a top level that is automatically wrapped by
another QGraphicsProxyWidget. This, we print from the list of items().
See also PYSIDE-86, PYSIDE-1887."""
