Standalone means
http://developer.sugarlabs.org/web-architecture.md.html#web%20activities%20standalone

It means you are using WebkitGTK1.  We encourage web development in
WebkitGTK2.  The WK1 is a fallback.

I suggest you do web development on sugar-build.  I guess some day XOs
will come with latest Fedora.  We can't rely in old Webkit because it
limits development.
