I just followed your steps to do the test, I followed all steps except step 7, since on my board, no need to run "netplan try" and "netplan apply", the eth0 and wlan0 already can get the ip from my router. Other steps are same.
I can't reproduce your problem, with the new installed 1012 kernel, no matter I plug ethernet or not, I can ssh to wlan0 always. I don't know why you have problem. When problem happens, you could check the /var/log/syslog, it should contain the log about getting the ip for eth0 and wlan0, maybe you could find sth is not correct in that log. for example: Nov 24 07:17:04 ubuntu systemd-networkd[1098]: eth0: Gained carrier Nov 24 07:17:04 ubuntu systemd-networkd[1098]: eth0: DHCPv4 address 192.168.1.106/24 via 192.168.1.1 Nov 24 07:17:04 ubuntu systemd-timesyncd[1141]: Network configuration changed, trying to establish connection.
