Verified 1.1ubuntu1.18.04.7~16.04.2 on Xenial. Installed a few linux packages, marked them auto-installed, ran /etc/kernel/postinst.d/apt-auto-removal , then booted to a old kernel. Apt would have removed it, but u-u did not. (The -34- kernel.)

Note: The workaround breaks autoremoving feature of new unneeded kernels in unattended-upgrades i.e. the setting 'Unattended-Upgrade::Remove-New-Unused-Dependencies "true"' (which is default in 16.04 unless 'Unattended-Upgrade::Remove-Unused-Dependencies "true"' is set in '/etc/apt/apt.conf.d/50unattended-upgrades'.
