QComboBox does not respect modelColumn() when using a multi column itemview as popup

void QComboBoxPrivate::setCurrentIndex(const QModelIndex &mi)
{
    Q_Q(QComboBox);

    QModelIndex normalized = q->model()->index(mi.row(),q->modelColumn(),mi.parent());
    if(!normalized.isValid())
         normalized = mi;    //fallback to passed index

    bool indexChanged = (normalized!= currentIndex);
    if (indexChanged)
        currentIndex = QPersistentModelIndex(normalized);
    if (lineEdit) {
        QString newText = q->itemText(normalized.row());
        if (lineEdit->text() != newText)
            lineEdit->setText(newText);
        updateLineEditGeometry();
    }
    if (indexChanged) {
        q->update();
        _q_emitCurrentIndexChanged(currentIndex);
    }
}
