Public bug reported:

Configuring login to suspend-then-hiberrnate when the lid is off and
configuring sleep so that hibernate happens 10 seconds after suspend,
when trying to test with:

sudo systemctl suspend-then-hibernate

I get:

Failed to suspend system, hibernate later via logind: Sleep verb
"suspend-then-hibernate" not supported

This could be a security vulnerability. If the user expects the system
to suspend (and then lock) when the lid is off and it does not work,
somebody could then just reopen the lid and get access.
