cloudflare include

# plugins/comet-cache/src/includes/traits/Plugin/AdminBarUtils.php

contains
wp_enqueue_script('chartjs', set_url_scheme('//cdnjs.cloudflare.com/ajax/libs/Chart.js/1.0.2/Chart.min.js'), [], null, true);

my editors complain that this leads to numerous alerts (cross domain loading issues, etc) …

Can this be turned off (there is a test around the enqueue)… Where ist it used? There is the test for ‘stats’ but I presume this is some kind of premium feature? If so, why ist it being enqueued for mere mortals?
