At one time, ath10k firmware had some weird logic related to trying to coordinate
4-way handshake with setting keys.  I'm not sure that was ever changed in upstream
firmware, so possibly you are hitting that bug/race.

We use recent supplicant and ath10k and do not notice any problems, but we also use
our modified ath10k firmware that changes how the 4-way and key-setting is handled,
as well as plenty of patches to ath10k driver that may or may not have some affect
on this path.

We also run with this supplicant patch, among a pile of others, possibly one of these makes
a difference:
