Yes, that's the + TR46 behavior.  

We're not changing the spoofable entries at this time due to security concerns.  You can register the ss version and it'll get there.  As a complete digression, IMO IDN/DNS should allow for a "display" form mechanism because the NFKC part of the mapping is a more than a bit destructive and there're a lot of other inputs that aren't going to look like the output.
