Lest anyone think that Chrome is being innovative here, this is Safari's default behavior for when the URL bar isn't focused. When you click on the URL bar, the subdomain, protocol, and path all appear.
Which drives me crazy, because my users send me screenshots in support requests. Now I have to spend even more time explaining to them how to click/copy/paste the URL. It was a terrible UX choice when Safari did it, and it's a terrible UX choice now that Chrome has done it.
Fortunately, it's trivial to toggle this setting in the Safari preferences--and then the full URL will appear by default.
A much saner behavior is to hide the URL entirely until focused, not to show a secretly mangled version.
