To call "render: layout => false" to correctly display the js.erb template in Rails 2.3.3

Question

I am running the last branch of Rails 2-3-stable (currently 2.3.3).

I am using jQuery to send an AJAX request to my "create" action, in which I have the following block:

respond_to do |format|
  format.js
end

I created create.js.erband to verify this action I added the following line:

alert('hello');

The request correctly enters the format.js block, but the answer tries to display the layout. Here is my log:

Jul 22 20:44:27 [2970] INFO: Rendering template within layouts/application
Jul 22 20:44:27 [2970] INFO: Rendering contacts/create

If I change my block respond_toto the following, it will work:

respond_to do |format|
  format.js { render :layout => false }
end

Is this the expected behavior or is it a bug in Rails? I would think that the fact that I am executing a JS response would be enough to set the layout to false.
