IFRAME
summary
Practical surprises and gotchas: tests across Chrome and Firefox show differing defaults for frameborder and inconsistent parsing of marginwidth percentages, 39 nested iframes expose that name-based targeting often resolves to the first match and can cross navigation boundaries, sandbox gives iframes a unique origin unless allow-same-origin is set, longdesc never forces a download, data: and javascript: src handling varies (IE blocks data:), fullscreen requires an explicit allow attribute, and srcdoc support and referer-policy behavior remain uneven across browsers.
