kreversi 19.12 fails to build at IconSize call

Hi,

kreversi release/19.12 branch fails to build with this error on CI:

 
pageItem->setIcon(QIcon::fromTheme(icon).pixmap(IconSize(KIconLoader::Toolbar)));
     error: IconSize was not declared in this scope

See 
https://build.kde.org/job/Applications/view/Everything%20-%20stable-kf5-qt5/job/kreversi/

Additionally, kwordquiz fails to build on Windows CI,
see 
https://build.kde.org/job/Applications/view/Everything%20-%20stable-kf5-qt5/job/kwordquiz/

I would be glad if someone could investigate these issues.

Thanks,
Christoph
