It looks they use /deep/ combinator, which is no longer supported in M60.

> [Deprecation] /deep/ combinator is no longer supported in CSS dynamic profile. It is now effectively no-op, acting as if it were a descendant combinator. You should consider to remove it. See https://www.chromestatus.com/features/4964279606312960 for more details.

Could we notify the site owner of https://www.chromeexperiments.com/ ? The site owners should update so that the site doesn't depend on /deep/.
