kssl and self-signed certificates

Hello, Using KDE 6 on Tumbleweed, there is no obvious way to configure trusted TLS certificates (https://bugs.kde.org/show_bug.cgi?id=482585), which results in annoying pop-ups when a self-signed certificate is used. kssl is using /etc/xdg/ksslcalist and /usr/share/kf5/kssl/ca-bundle.crt to store certificates, so should I edit them directly?
