Some of these UNLIKELYs seem questionable. I could imagine content where custom element definitions are common.

Spelling 'document'
The comment is too vague, please clarify.
Please move FIXME to a line of its own and use { }

> Source/WebCore/html/parser/HTMLDocumentParser.cpp:201
> +        ASSERT(newElement);

This assert adds no value given the code above.

> Source/WebCore/html/parser/HTMLStackItem.h:105
> +    const AtomicString& namespaceURI = element.get().namespaceURI();

auto&
