Constant vars are never saved, but nice find.

Ah, I found out what's happening here. I don't have a fix right away, but I did find this note under issaved():

//use save idx even though we are getting value because that handles lists correctly
//TODO: should make this work for consts and other non-writable values

I don't understand why lists wouldn't be handled correctly without this, so that's something I'd have to investigate.
