      QJsonObject::fromVariantMap seems to cause the ulonglong values from the variant map appear signed within the resulting json object. In contrast the ulonglong value can be inserted into a QJsonObject pretty much any other way and it'll remain unsigned.

      This problem does not appear at least in Qt 5.14.0, Qt 5.12.9 or Qt 5.12.5.

      Steps to reproduce the issue:

      • Run the attached project
