example 14 - iFrame in head

iFrame breaking the head

rendered HTML-Tags in the head (opposed to in the body) will break anything beyond that point. So if an iFrame would be placed in the head before the meta robots, the meta tag will be pushed into the body but will be used nevertheless.

Google Search Console URL Inspection will declare this Excluded by ‘noindex’ tag which is confusing because the iFrame didn't seem to break the head.
