It seems it is resolved in GTK+ 3, but I am unable to confirm since I'm still on GTK+ 2.x. Can you try with GTK+ 3? It's possible with GTK+ 3 it still may not work since we might have to change it from hardcoded to dynamic to take advantage of the fix.
Known limitation with GTK+. I even filed a bug for it in GTK+ earlier this year:
