The following pages contain a HTML iframe, injected via an authorised script. We need to make a note of them, because iframes require an extension when running in AMP mode. It is usually, but not exclusively, invoked via Template:Services or Template:Infobox.
All MSO iframes are security-locked and can't be used to load custom webpages.
