No, that's due to Ghostery. Recognized it as soon as I saw your image. Ghostery breaks lots of sites, even those it isn't explicitly blocking.
However, in this case, CSS and JS from ChartBeat is being blocked because it's one of the tracking services that Ghostery disallows. You can whitelist, but this is probably the "correct" behaviour if you want to block tracking services.
Given Ghostery's popularity, I would almost venture to blame the website for this unintended behavior, not the plugin--even if they're keeping to standards and good behavior.
