webkit receives limited support. For details, see https://wiki.ubuntu.com/SecurityTeam/FAQ#webkit webkit in Ubuntu uses the JavaScriptCore (JSC) engine, not V8

It is no longer possible to build new webkit2gtk versions on focal and earlier. Marking as ignored. wpewebkit isn't used by anything of importance in the archive, except for cog, an example container for wpewebkit. There is no point in attempting to backport newer wpewebkit versions to the archive. As such, marking as ignored. It is not feasible to fix webkitgtk, qtwebkit-source, and qtwebkit-opensource-src. Marking them as ignored.
