I think you're right.  Please file a bug.

Note that when multiple monitors are combined into an X screen with
Xinerama, it is possible (though rare) for a single character to span
multiple screens.  I guess the part lying on each screen should be
rendered with the correct option for that screen.  That may take some
work to implement.
