Comment:

 As Samuel mentioned Sugar currently uses a
 [https://wiki.sugarlabs.org/go/Development_Team/Low-
 level_Activity_API#X_Properties custom protocol] for startup notification,
 so the behaviour you see is as-designed. Using a standard protocol is
 planned (#2434), but nobody has done the implementation work yet.
 A quick & dirty workaround would be to map an X window with the custom
 properties in a wrapper script. A less quick hack would be an LD_PRELOAD
 wrapper that interjects X11 calls and adds the custom properties.
 libsugarize
 [http://dev.laptop.org/git/users/albert/sugarize/tree/xlogo.activity/libsugarize.c
 seems to implement] the latter option.
