No it uses scripts from parastorage.com (part of wix).
Welcome to the web in recent years. Looking at my umatrix rules, for basic functionality a lot of sites need scripts from ajax.googleapis.com, [cdnjs.]cloudflare.com, brightcovecdn.com, static.parastorage.com (as in this site), and many other cdns besides.
As is often the case, Firefox's Reader View fixes the problem.
