The problem is related to select2/select2#2750

We need to change the way solidus init the select2().
To solve this specific problem is enough to override the backend/app/views/spree/admin/products/new.js.erb and change $('.select2').select2(); to $('select.select2').select2();

I am changing all the points where solidus uses $('.select2').select2(); to $('select.select2').select2(); and then I'll open a PR
