Would those of you who consider yourselves RegExp experts take a look at https://bugs.ecmascript.org/show_bug.cgi?id=3519  Is this a bug? If so, what is the fix?

This construction for Identity Escape goes back to Norbert's original proposal http://norbertlindenberg.com/2012/05/ecmascript-supplementary-characters/index.html
