I would think this is by design like that.

What is the issue? You unplug the device from AC with lid closed and it
wakes up? Userspace should put it back to sleep in these cases. In Windows
and ChromeOS there is something called "dark resume" that deals with this
but I'm not sure if generic distros have that yet.
