// a systemd unit name for those, otherwise it will use an empty string as the
// ID which is problematic because it may collide with other apps that don't run
// under a unit. Also, if using a desktop environment like GNOME or KDE, a
// systemd scope gets created when spawning via the application launcher. Child
// processes also inherit the scope, so if the app launcher creates a terminal
// which the user launches the browser with, then the browser will incorrectly
// get the terminal name. This function caches it's results and may be called
// more than once, but must be called on the same sequence.
