As a workaround I opted for using a systemd unit file to create a loose
dependency between containerd and dockerd.
Here's how:
As root:
Make the override directory (permission 755)
mkdir /etc/systemd/system/containerd.service.d/
Create the override file in the above directory (permissions 644)
vi override.conf
Add the following to the file
[Unit]
Before=docker.service
Wants=docker.service
Restart systemd daemon
systemctl daemon-reload
Check it works
Stop containerd
systemctl stop containerd
Check dockerd has stopped
systemctl status docker
Start containerd
systemctl start containerd
Check dockerd has started
systemctl status docker

Title:
docker stopped when containerd updated
Status in unattended-upgrades package in Ubuntu:
Confirmed
Bug description:
When containerd was updated in my bionic instance it stopped docker
then stopped containerd. When it was done updating containerd it
brought it back online. docker stayed stopped.
2020-04-03 06:20:32,973 INFO Packages that will be upgraded: apport
containerd python3-apport python3-problem-report
An eoan installation that didn't have this problem had this line:
2020-04-03 06:06:01,612 INFO Packages that will be upgraded: apport
python3-apport python3-problem-report
So the main difference is that containerd was updated.
At the end of this systemctl --all reported docker as:
docker.service loaded inactive dead
and containerd as:
containerd.service loaded active running
