But then the sandbox code should be linked in even if there are some
symbols (e.g. from X11) not available...

In general I have X11 and wayland disabled in the port options, except
in some strategic places which resulted in build failures before.
Seems some ports have changed regarding this and I need to find out
what causes the sandbox code not to be included. I see references to
X11 libs in the webengine libs, so :
