With pref 'privacy.firstparty.isolate.restrict_opener_access' set to 'false' this is still reproducible. After entering facebook credentials and hitting login, as.com login webpage refreshes and does not login. Using Tor browser, the user is successfully logged in to As.com after entering Facebook credentials. Removing tracking status for 52 and 53 since this does not affect normal users.
This website can log in successfully when I disabled third party cookies. So, I believe that the login mechanism of 'as.com' is depending on third party cookies. And when we disable third party cookies, it will detect it and use a different way other than third party cookies to log in.
