Oops. @Hainish you included broken code from #10852. Roll it back in the release branch but not in master.

@koops76 this was not included in the 2017.7.5 release, and was not included in the release branch, which is only used for the HTTPS Everywhere Atlas.

Just wondering why a lot of rulesets have suddenly failed tests and been put into the experimental section?

[Hainish]

@BK1233 see #10538
