The following reply was made to PR port-evbarm/57308; it has been noted by GNATS.
As expected, after dhcpcd update from above suggestion there is no

completed:

The PI3 is of course in the same spot, not moved, not touched.
Restarting wpa_supplicant helps:
rpi3# service wpa_supplicant restart
Stopping wpa_supplicant.
Starting wpa_supplicant.
