Dir View Example is not working correctly

[megapro17]

Problem is, that there is no icons, as in example. I tried even writing own icon provider, and seems that it don't work correctly anyway. Qt version is 6.0.4

How it looks from example:

And mine:

#include <QApplication>
#include <QFileSystemModel>
#include <QFileIconProvider>
#include <QTreeView>
#include <QCommandLineParser>
#include <QCommandLineOption>


int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    QFileSystemModel model;
    QFileIconProvider iconProvider;
    model.setIconProvider(&iconProvider);
    model.setRootPath("");

    QTreeView tree;
    tree.setModel(&model);
    tree.resize(800,500);
    tree.setWindowTitle(QObject::tr("Dir View"));
    tree.show();

    return app.exec();
}

Hi
The same code shows icons in 5.12.2 so seems to be a Qt6 thing.
I tried to search https://bugreports.qt.io/ but didnt see a report.
