https://git.drupalcode.org/project/blazy/-/blob/8.x-2.x/CHANGELOG.txt#L93

• Fixed for regression with lightboxes and iframes.
• Cleaned up irrelevant iframe attributes due to iframe within iframe since 8.6.
• Removed useless iframe for when Image to iframe is enabled to save few bytes.
• Added supports for iframe only without Image to iframe for uncool people.
• Removed no longer relevant autoplay_url check which is now done within iframe.
• Updated hard-coded iframe so that can be cleanly removed via variables.
