Comment (by westonruter):

 @jordantrask WordPress adds the CSP header itself in
 `WP_Customize_Manager:: filter_iframe_security_headers ()`:
 https://github.com/xwp/wordpress-develop/blob/4.7.3/src/wp-includes/class-
 wp-customize-manager.php#L1609

 Is the ancestor frame not <https://domain.com>? What is the `src` of the
 `iframe` that is being loaded? The workaround plugin is designed to make
 the `home` URL and `siteurl` be the same.
