This isn't the super-key related bug, and in fact they shouldn't have
been merged.  No amount of changes on our side can work around input
methods swallowing the shift modifier in "C-S-u" and the "kp-" in
"kp-separator".

I'm trying to figure out how all of that fits together in Wayland to
hopefully fix it in GTK upstream.  Hard-coding real modifier values is
very fundamentally wrong under both X and GTK, and leads to extremely
hard-to-diagnose problems down-the-road.
