Current/Missing Behavior

On Wayland, app_id must be available for desktop environments to match an application to its desktop file for things like icons etc to be resolvable. The property is similar to WM_CLASS for X11, and indeed must map 1:1 to the .desktop basename, and to the StartupWMClass property within the .desktop file when it exists.

Expected/Proposed Behavior

nw.js applications should return an app_id
