If a ssh key has a comment like "Tim Test" ssh-import-id returns 1 and adds the key to the root user without the the login message "Please login as the user "xxxx" rather than the user "root".

if there is a space in the comment portion of an ssh_authorized_key, then the adding of a prefix is broken. That prefix would normally provide the way to provide the "please login as user 'ubuntu'" message. Instead, the user can go right in as root.
Reproduce cloud-config is:
#cloud-config
ssh_authorized_keys:
- ssh-rsa AAAAB3NzaC1yc2EAAAABIwAAAQEA3I7VUf2l5gSn5uavROsc5HRDpZdQueUq5ozemNSj8T7enqKHOEaFoU2VoPgGEWC9RyzSQVeyD6s7APMcE82EtmW4skVEgEGSbDc1pvxzxtchBj78hJP6Cf5TCMFSXw+Fz5rF1dR23QDbN1mkHs7adr8GW4kSWqU7Q7NDwfIrJJtO7Hi42GyXtvEONHbiRPOe8stqUly7MvUoN+5kfjBM8Qqpfl2+FNhTYWpMfYdPUnE7u536WqzFmsaqJctz3gBxH9Ex7dFtrxR4qiqEr9Qtlu3xGn7Bw07/+i1D+ey3ONkZLN+LQ714cgj8fRS4Hj29SCmXp5Kt5/82cD/VN3NtHw== Scott Moser
After boot, you'll see that this key is present without the prefix, and the holder of that key can go in as root.
