I’ve drafted but not published a long list of problems I’ve experienced with Ubuntu 18.04. In short it’s been one of the worst desktop releases of Ubuntu I’ve used. My experience on servers has been fine. Anyway I haven’t looked into the details of these patches but:

• libwebkit2gtk-4.0-37:amd64 (2.22.6-0ubuntu0.18.04.1)
• libjavascriptcoregtk-4.0-18:amd64 (2.22.6-0ubuntu0.18.04.1)

These package releases seem to have fixed some of my issues that have been present since May 2018. In particular Liferea has been broken on my desktop for that long. Better late than never I guess.
