CTRL-EVENT-SIGNAL-CHANGE flood in logs

[dodgy-cane-freebee at duck.com]

Hello. I am using wpa_supplicant version v2.11-hostap_2_11+ (package version 2:2.11-3) with NetworkManager on Arch Linux with default settings. I'm experiencing an issue where my entire journalctl log is constantly flooded with repetitive messages:
$ journalctl -u wpa_supplicant | grep CTRL-EVENT-SIGNAL-CHANGE | wc -l
3363932
$ journalctl -b | tail -n 20
