QComboBox::findData behavior change undocumented or unintended

With 4a69cd7f7 (from QTBUG-84636), QVariants were changed to not compare between types anymore as documented in the commit. As a result of that, QAbstractItemModel::match and QComboBox::findData change behavior as well, with QComboBox::findData calling QAbstractItemModel::match. In this case however, the documentation for these functions does not seem to reflect the QVariant behavior change.

It is unclear if the behavior change in QAbstractItemModel::match and QComboBox::findData is undocumented, implied with the QVariant change, or unintended.

Simple reproducer:

    QComboBox *combo = new QComboBox(this);
    combo->addItem("Text", 50);

    QByteArray byteArray = "50";
    int idx = combo->findData(byteArray);
    if(idx == 0)
        std::cout << "Found. Qt 5" << std::endl;
    else if (idx == -1)
        std::cout << "Not found. Qt 6" << std::endl;
