GtkMenuShell is parent class of GtkMenu. Maybe one of [1] is what you want ("deactivate", "cancel"); can't test myself.
If not, and assuming double updates are evil, test whether "hide" and optional activation emissions both appear in same iteration of main loop -- if so, you can play with g_idle_add() to set final value:

before popup -> set default value to tmp
on optional activate -> set activated value to tmp
... (iteration ends)
on high-priority idle -> set final value from tmp
