I'm using the ec2 plugin, so I don't know if this issue is a core issue or an ec2 issue.
When I click in "Prepare to Shutdown", if there are jobs in the queue, Jenkins still launch slaves.
I think in shutdown mode, this process shouldn't proceed.
This is still a valid problem. This can incur a lot of aws cost if you are trying to shut down and jobs pile up in the queue. I still see this frequently.
