Unfortunately, it's the same with xmodmap. The third-level 
chooser stops working in untrusted clients.

The modmap is loaded from a trusted client and works well then 
for any trusted client. For untrusted clients, all modifications 
done by the modmap -- save the third-level chooser! -- also work.

I feel that this classifies as a bug. I'll file a formal report
