I cannot reproduce this. Could you obtain tracing information
("trace-cmd record -e cfg80211") on an affected system?
Also a wpa_supplicant debug log would be helpful. Or better yet, use a
new supplicant with the "-T" parameter -- this will make its debug
information go into the cfg80211 tracing that you record as per above.
