 Replying to myself: After some more digging it turns out that Session ID
 tracking and tracking via TLS resumption are different beasts (see:
 https://tools.ietf.org/html/rfc5077 especially sections 3.4 and 5.8). That
 would explain the still available session ID mentioned above even if the
 pref in question is disabled.
