Running

KMessageDialog *dialog = new KMessageDialog(KMessageDialog::WarningTwoActionsCancel, QStringLiteral("Hello"));
QObject::connect(dialog, &QDialog::finished, [](int result){
    qWarning() << "res" << result;
});
dialog->show();

and then pressing Esc to close the dialog will print twice. One time with result QDialogButtonBox::Cancel, another time with 0.

This does not happen when clicking the cancel button
