To work around this issue in cloud-init 20.4 on azure, one can launch a VM providing cloud-config userdata which contains the unsplit pubkey content.

userdata can be added in the Advanced tab in Azure portal dashboard or on the az cli via the cmdline parameters --custom-data mycloudconfig.yaml

For the auto-generated key listed in the above bug description the following would be the "right" #cloud-config to provide at VM launch time

#cloud-config
ssh_authorized_keys:
