"A stop job is running for /dev/zram0" after everything is already unmounted slows down shutdown process

I notice this is one of the last things in the shutdown sequence after "Reached target System Shutdown" is shown. All filesystems are already unmounted, yet this "A stop job is running for /dev/zram0" can easily delay shutdown/reboot by 15-20 seconds.

Is there any way to force this to skip whatever cleanup it wants to do? With all the filesystems unmounted already, I don't understand what the point is of waiting.
