    Description

      Since upgrading from Qt 6.3.2 to 6.4.1 I started notice Qt wanings at app startup:

      QWebEngineCertificateError is neither a QObject, nor default- and copy-constructible. You should not use it as a QML type.
QWebEngineFullScreenRequest is neither a QObject, nor default- and copy-constructible. You should not use it as a QML type.
QWebEngineLoadingInfo is neither a QObject, nor default- and copy-constructible. You should not use it as a QML type.

      Stack:
