@Stefan,
I just did the test according to your description, I didn't reproduce
your problem:
On my rpi4B with 4G ram and without ethernet cable connect, I installed
the 1012 kernel:

Title:
No connection through SSH over WIfi after kernel update
Status in linux-raspi2 package in Ubuntu:
Incomplete
Bug description:
After updating from kernel "linux-image-5.3.0-1007-raspi2" to "linux-
image-5.3.0-1012-raspi2" I no longer can establish SSH connection to
Raspberry over Wifi.
When it is on wired connection, SSH works and initial screen shows
that both adapters (eth0 and wlan0) are connected and have their IPs.
"ifconfig" confirms that both adapters are up and have their IPs.
Establishing SSH session with both IPs is successful.
When I disconnect the network cable, SSH is no longer possible
(connection time out). In the same time the router is showing that the
Raspberry is connected to the Wifi network.
Plugging back the wire does not make the SSH possible. A restart of
the Raspberry is required with plugged in network cable in order to
establish SSH again.
The system is Raspberry Pi 4, 4GB with Ubuntu server X64 image - clean
install.
Wifi was enabled by editing /etc/netplan/50-cloud-init.yaml and
running "sudo netplan apply"
