This implements the "Alt" behavior for the "Reboot" button as outlined in the design here: https://wiki.gnome.org/Design/OS/BootOptions Note I've tried implemeting this with the AltSwitcher class from js/ui/status/system.js first, but that puts the button in a St.Bin() which causes the button to think it is the only button on the dialog and makes it have rounded corners on both of its bottom corners. https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/199
