It does not. :-(
When `org-babel-exp-process-buffer' runs (under `org-export-as'), all the
header info is dropped.
There might be a way to backtrack from the copy buffer to the original and
remap the src blocks, but it seems like the wrong way to go. It would be a
lot of work, I think.

I think the better way to go is to do all the formatting in babel. That
is, make a babel src block handle the formatting for you and subvert the
normal mechanisms.
To do this, write a src block that is given the name of another src
block, that grabs the body (and if you really need it the header
info), formats it as you need, and inserts it in final form wrapped
in an `export html' block.
So if you had a src block named `codeA' and one named `klipsify' which
has the code needed to render the output you desire depending on the
value of
: :var src-blk-name="my-codes"
then a
#+CALL:klipsify("codeA")
line will put the output in the exported document.
Something like this:
#+NAME: codeA
#+BEGIN_SRC: javascript :eval never-export :exports none
console.log("success");
#+END_SRC
#+NAME: klipsify
#+header: :var src-blk-name="my-code" :exports none
#+header: :results raw :wrap export html
#+BEGIN_SRC emacs-lisp
(save-excursion
(org-babel-goto-named-src-block
src-block-name)
(let ((body-code
(org-babel-expand-src-block)))
(klipsify-my-code body-code)))
#+END_SRC
Obviously, you need to defun `klipsify-my-code' or whatever.
All the code blocks would need to be named and have these headers:
: :eval never-export :exports none
or maybe
: :exports results
You would use the latter, if you want the results of evaluating the code
to appear in the exported document. Put the #+CALL line just before the
code block and then the code will appear first and the results next.
HTH,
Chuck
