LXQt ignores Qt5 theming after 24.0.0 update

kvantum-qt5 is installed. Some applications have a setting to force it and they do show the correct theme. Some applications like the manjaro-settings-manager and Virtualbox do not have the setting and appear with the wrong theme.

LXQt is now version 2.0 and based on Qt6.

That creates some inconsistencies - I have been struggling myself with some - I haven’t hit the ore yet.
