Hey thanks for the response, but I think that could potentially lead to more problems because I'm sure a lot of other things are dependent on the class/ID. Is there a way to find the specific bit of code doing that animation?
I have removed the following two lines of code and still getting the same issue
$single_variation_wrap.slideDown('200').trigger( 'show_variation', [ variation ] );
$variation_form.find('.single_variation_wrap').slideUp('200');
Here's a test page
