Akamai ruleset breaks steamcommunity.com in plaintext HTTP
I get a CSP error when loading steamcommunity urls over HTTP. HTTPS Everywhere has Steam and Steam Community rulesets disabled by default, but Akamai is enabled. Steam's servers send CSP headers for http://akamai when accessed over HTTP, and https://akamai when accessed over HTTPS.
Page works if I enable Steam and Steam Community rulesets.
I am unable to include CSP headers in the ticket description because Trac flags the ticket as spam. If possible, I will include headers in comments.
