Inconsistent behavior for .onion and .onion. (with tailing dot) hosts #13568

Description

@cschanaj

Type: code issue

Domain: onion.

As per the following code, we do not cancel .onion requests in "Block all unencrypted requests" mode even if they are not available in HTTPS. However, the same does not hold true for .onion. (with tailing dot) requests. Requests to .onion. are forced to go through HTTPS (main_frame) or otherwise canceled if there is no applicable ruleset.

var shouldCancel = (
httpNowhereOn &&
uri.protocol === 'http:' &&
!/\.onion$/.test(uri.hostname) &&
!/^localhost$/.test(uri.hostname) &&
!/^127(\.[0-9]{1,3}){3}$/.test(uri.hostname) &&
!/^0\.0\.0\.0$/.test(uri.hostname)
);

e.g.

http://nonhttpsonionaddress.onion/ -> http://nonhttpsonionaddress.onion/

http://nonhttpsonionaddress.onion./ -> https://nonhttpsonionaddress.onion/

P.S. I am not really sure if this is the expected behavior. @Hainish @cowlicks can you confirm?

P.S.2 Possible fix in #13569
