     * it is possible that some archives have no data yet, but at a later time there might be actually archived data.
     * As we never reload the initial list of widgets we would still not show the widget even there we should. Example:
     * On page load there are no conversions, a few minutes later there might be conversions. As the middleware is
     * executed before showing it, we detect correctly that there are now conversions whereas `isEnabled` is only
     * checked once on the initial Piwik page load.
