--- Comment #4 from Henri Verbeet hverbeet@gmail.com --- https://bugzilla.gnome.org/show_bug.cgi?id=722636#c10 appears to refer to some standard introducing a relation between .desktop files and WM_CLASS, but as far as I'm aware that's purely a gnome-shell heuristic that just happens to work in a lot of cases. Does anyone know if that comment is referring to an actual standard?
