Is this really a bug?.
From the xl(1) man page.
shutdown [OPTIONS] -a|domain-id Gracefully shuts down a domain. This coordinates with the domain OS to perform graceful shutdown, so there is no guarantee that it will succeed, and may take a variable length of time depending on what services must be shutdown in the domain.
Seems like ignoring a shutdown request when the guest cannot yet shutdown gracefully is the expected behaviour.
This also doesn't seem sufficient. SYSTEM_RUNNING is set prior to starting init in an initramfs and orderly_power_off(false) will still likely fail at this point.
