 That's because you didn't read #3455. It describes how Tor Browser is
 going to use the feature. Third party elements (user link-click
 navigation) would all share the same circuit, because they all share
 referers.

 However, I'll add a note in #3455 that we'll need to still force this
 binding if users somehow disable referers.. That's going to be a pain,
 though, because there are lots of ways referers can get spoofed/disabled
 by wacky third party addons...
