The closest the spec comes to specifying this HTML-entity-ification is in example #298 under Backslash escapes, where a careful observer sees that three characters are not just escaped by a backslash, but are replaced with HTML entity references.
I would expect this behavior to be spelled out in perhaps one of the following sections: Backslash escapes, Entity and numeric character references, Raw HTML, or Textual content (the most likely). But it is not spec’ed in any of those sections.
