This is great!  I tried it out last night a bit.

Yes, I went to acid 0.  I think we are very close.  'last' and 
'penultimate' did not used to have anything in them correctly, and now 
they do.  The assertion at the end that uses computedStyle would even work 
if the property being retrieved happened to be one of the ones propagated 
by our CSS code.  qS("#instructions:last-child") returns zero elements. 
It isn't picking up penultimate.  But all of the earlier steps prior to 
the last line are working.

Aha!  I found something out about this.  There is this DOM 
implementation by Thatcher et al, called env.js.  I used it a couple of 
years ago with an edbrowse 3.3.1 before we started ours.  I learned a lot 
from using it.  They have CSS-related code, and they have the following 
internal routines:

var __toCamelCase__ = function(name) {
     if (name) {
         return name.replace(/\-(\w)/g, function(all, letter) {
             return letter.toUpperCase();
         });
     }
     return name;
};

var __toDashed__ = function(camelCaseName) {
     if (camelCaseName) {
         return camelCaseName.replace(/[A-Z]/g, function(all) {
             return '-' + all.toLowerCase();
         });
     }
     return camelCaseName;
};


So I conclude that formalized conversion of camel case to/from dashed CSS 
is a thing.  I think that may be the missing link or one of them.
