Amazon Web Services ruleset breaks Anvato video player

[practik]

Anvato is a media-streaming company whose HTML5 video platform is used by a number of local TV stations across the U.S. I tested the websites of three different stations that use it (krqe.com, wkbn.com, wspa.com) and found that video would not work on them unless I disabled HTTPS Everywhere's rule for Amazon Web Services – see screenshots. This is on Firefox 55.

@J0WI, #14656 fixed this as well.
