QDir::cleanPath does not handle single-dot (current dir ) consistently

#include <QtCore>

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

    QString path ="/GeneratedFiles/./and";
    qDebug()<<QDir::cleanPath(path);
    path ="./GeneratedFiles/..";
    qDebug()<<QDir::cleanPath(path);// prints "./GeneratedFiles/..";

    path ="./GeneratedFiles/../";
    qDebug()<<QDir::cleanPath(path);// prints "";
    return app.exec ();
}
