I reproduced on the last set of pages you sent me until i removed this line:
js.src = "//connect.facebook.net/en_US/all.js#xfbml=1";
after removing that line, the problem stopped.
Since you are using super suite, a work around to prevent the problem from being able to happen would be to create the form on a blank page, and use framework builder to add it to the order page asa plugin.
create a new blank page named contactForm.php (some people like to put plugin pages in a sub directory, plugins/contactForm.php)
add the form to this page.
then on the orders page, add a plugin, go to WebAssist -> framework Builder -> Plugins -> Insert Plugin. For the plug in source select the contactForm page.
