Unsanitized HTML parsing

Newly Available (since 2025-09-15)
Expected to be Widely Available on 2028-03-15

The Document.parseHTMLUnsafe() static method parses HTML into a DOM tree, much like the setHTMLUnsafe() DOM method inserts HTML into an existing tree. No sanitization applies, so never call it with user-provided strings.
