Hello Erik,
the current version of Konqueror uses QtWebEngine by default. I fear that 
kwebkitpart may have been removed from it (for instance, I know it's been 
removed from Gentoo). In the weekend, I'll try to install an Ubuntu virtual 
machine with both Ubuntu 20.04 and 16.04 to check what the situation is.
