Issue when removing row from ComboBox model

Question

I have an ComboBox in my QML file:

import QtQuick 2.4
import QtQuick.Controls 2.0
// ...
ComboBox {
    id: serailPortNameBox
    model: availableSerialPortsModel
    textRole: "display"
}

and model availableSerialPortsModel that contains serial port names currently available in system:

QStringListModel availableSerialPortsModel;
QList<QSerialPortInfo> portsList = QSerialPortInfo::availablePorts();
for (auto port : portsList) {
    int row = availableSerialPortsModel.rowCount();
    availableSerialPortsModel.insertRow(row);
    QModelIndex index = availableSerialPortsModel.index(row);
    availableSerialPortsModel.setData(index, port.portName(), Qt::DisplayRole);
}
// ...
engine.rootContext()->setContextProperty("availableSerialPortsModel", availableSerialPortsModel);

When I'm removing some serial port:

for (int row = availableSerialPortsModel.rowCount() - 1; row >= 0; --row) {
    QModelIndex index = availableSerialPortsModel.index(row);
    QString name = availableSerialPortsModel.data(index, Qt::DisplayRole).toString();

    if (portsToRemove.contains(name)) {
        availableSerialPortsModel.removeRow(row);
    }
}

ComboBox removes this port with some visual issue:

Is it just a bug og ComboBox or am I doing something wrong? My Qt version is 5.7.0 on a Apple device with Sierra 10.12.2.

Here a simple project that reproduces the issue.

This is Qt 5.7.0 bug (bugreports.qt.io/browse/QTBUG-54573). Upgrading to Qt 5.7.1 id solved the problem.
