Hello
I've been testing out WPA3/WPA2-mixed networks on my OpenWrt router, and I noticed whenever I enable 802.11r the network doesn't show up in the list of Wi-Fi networks in NetworkManager. I initially thought this was due to some bug with wpa_supplicant, but running "iw dev wlp18s0 scan" also fails to list the network. If I'm not mistaken, iw doesn't use wpa_supplicant to scan for networks, so that rules out wpa_supplicant. That means something deeper in the stack is causing this, and my guess falls on iwlwifi. I'm listing what I think is relevant system info below (please let me know if there's anything else that's missing):

This is what "iw dev wlp18s0 scan" outputs when 802.11r is disabled and it's able to see the network:
