Condition 'ba.isEmpty()' is always false" false positiv with QByteArray

[Vincas Dargis]

With Cppcheck 2.9 I get false positive within Qt 5.15 application code:

Condition 'ba.isEmpty()' is always false

For this function:

QImage deserializeImage(const QVariant &data) {

    if (data.isNull())
        return QImage{};

    const QByteArray ba{data.toByteArray()};
    if (ba.isEmpty())
        return QImage{};

    return QImage::fromData(ba, "PNG");
}

I've attached example application project.
