When a VPN app is doing DNS with its own tunnel servers, protecting that traffic can result in the tunnel and tunnel DNS server IP addresses leaking. Any VPN app that is setting tunnel DNS servers that aren't reachable through the tunnel is already broken, as apps would be unable to do DNS when leak blocking is enabled.
