Looks more like an AP bug to me..

Either the AP did not receive the first EAPOL-Key 4/4 or processed it
only after retransmitting 3/4. Supplicant side will need to to reply to
retransmitted 3/4 to complete the 4-way handshake. If the AP received
either of these 4/4 messages, it should be fine with the result. If it
didn't receive either, it should disconnect the station. It does not
look like either of those happened.
