Instrument org-export-as. Then step thru it.

Before this line:
 
 (org-export-execute-babel-code)

the buffer copy ( my-buffer<2>, say ) will show the parameters/headers.

After that line is executed, they are gone.

You can work around this by `advicing' various babel functions and inserting
things you want to save as attributes, but it would be nice not to need
to do that.

HTH,
