screen is not locked on laptop if context menu (right click menu) is active

[Tihomir Rabuzin]

I'm on a laptop and if I accidentally activate right click (contextual) menu on desktop window or in file explorer while closing the laptop lid, the laptop will go into sleep mode but after reopening it screen will lit up and desktop/window would be presented without any need to reenter user credentials (password) on lock screen.

That happened on HP ProBook 6570b with ubuntu mate 16.04 LTS 64bit (updated to 16.04.2)
and dell inspiron 3000 series with a completely new (clean) install of latest (16.04.2) version of 64bit ubuntu mate.

I can't reproduce this on 17.10 daily. What Window Manager are you using?
