Enabling this does set the title of the iframe on the parent page once available. This feature works on the same and the remote domain. The original title is shown until the new one is loaded. The original title cannot be hidden as this would be a global setting and also affecting all pages of a website. Shortcode attribute: use_iframe_title_for_parent="same". For the external workaround you need to set it to "Remote Domain" or set use_iframe_title_for_parent="remote" AND use_iframe_title_for_parent="remote" in the ai_external.js settings. Since 2026.0 the shortcode setting is mandatory if you configure ai_external.js because of security reasons.
