Conflict with Disqus

It seems that the public preview links mistakenly load the Disqus comments, thus create an identifier when we visit the preview link. This will cause some conflicts, see this page: https://help.disqus.com/customer/portal/articles/662547-why-are-the-same-comments-showing-up-on-multiple-pages . Please somehow disable the comments from loading in these Public Preview links, thanks!
