[webkit-gtk] Nothing shown in the widget when compiling with Fedora 37

[Lothar Scholz]

Hello,

So after a year of silence i tried again to get things going in the
hope that it now reached some workable out of the box state. But using
the CMakeLists.txt and C++ Code below it compiles and runs, it does
only show a naked empty window.

By the way, where is the example code from the website? It seems they
are removed.
