• Fix: V2Ray's Hysteria 2 PR causes traffic loopback when using system stack. (V2Ray has poor support for UDP-based transport, e.g. no proxySettings support and no sockopt support, so don't use it for proxy chain.)
• Try to fix traffic loopback when server address is a domain.
  • By adding a custom detour function (force-use a specified outbound) to DNS servers.
  • By reverting a fix for DNS rules matching priority. Some functions rely on the behavior of this bug. (See v2fly/v2ray-core issue 1558 and 1855.)
  • For a long time, SagerNet's IPOnDemand is somehow meaningless because it adds some IP rules with high priority. Still thinking how to fix that.
• Some other bug fixes.
