The last commit will fix the issue. I am not using ajax_command_replace() anymore for replacing the cart content. I have introduced a new Ajax command dc_ajax_add_cart_command_html() that does the same thing as ajax_command_replace(), just it won't add an extra wrapper div with style display: block.

The code needs to be optimized, and automated tests needs to be written. I will carry them out in another issue.
