Comment (by cypherpunks):

 1. This fix can't to prevent fingerprinting for environment where
 Torbrowser used without proxy, like Transparent proxy or something.
 2. Tor is not nanny to control what does Torbrowser and it depends
 ClientRejectInternalAddresses option, yet it loudly yells to user because
 it's bug to surf localhost over Tor.

 If you want to deny localhost connection attempts then find way to deny it
 actually without reinventing any security holes.

 It especially fun with fix for #10682.
