I remember it used to work, but it doesn't work in current master.
Aditya, Is it possible that one of your recent change to admin console broke this ?
Is it the Shutdown button in Settings? Works for me in a build from yesterday when run via make run.
no, i am talking about right click on document and then kill from the context menu poppped up
