I do see one of these (which, I'd assume, is actually expected if you
have something on the system that runs to transmit before 4-way
handshake is completed).

But this does not show up in my tests with mac80211_hwsim and the
current wireless-testing.git and hostap.git snapshots.

Did you confirm that the latest snapshot works with this reverted?

Since I was unable to reproduce, some more debug output could be
useful. Please at least verify that the STA entry for the AP is not
marked authorized. The next step would be to check whether sta_set_flags
in wpa_supplicant driver_nl80211.c is failing. Unfortunately, it looks
like the current implementation does not make this very clear in the
debug log, so some additional prints may be needed there.

Please also describe the security configuration (WPA2-Personal/CCMP?)
that you are using.
