I have similar problem, google insights shows the problems with rendering:
https://static.hsstatic.net/…-libs/static-1.4/jquery/jquery-1.11.2.js
https://static.hsstatic.net/…sets/static-1.4049/css/public_common.css
Why jquery is included in the header instead of the footer and why it is not possible to delete/uncheck the jquery from header and include it in the footer?
It is quite big issue if I can not optimize my website.
