The crypto retransmission timer doesn't use max_ack_delay intentionally, see: https://tools.ietf.org/html/draft-ietf-quic-recovery-20#section-4.1

 "In order to quickly complete the handshake and avoid spurious
   retransmissions due to crypto retransmission timeouts, crypto packets
   SHOULD use a very short ack delay, such as the local timer
   granularity.  ACK frames SHOULD be sent immediately when the crypto
   stack indicates all data for that packet number space has been
   received.
