The GDK and hence GNOME standard is that keys that begin with XF86 according to libxkbcommon not prefixed with XF86, though gdk_keyval_from_name() strips XF86 if provided. If libxkbcommon doesn't recognize the accelerator name without XF86, try again adding XF86 to the start. This restores compatibility with gnome-settings-daemon, schemas, and existing user configuration. https://bugzilla.gnome.org/show_bug.cgi?id=727993
