> Where do the standards say it ought to work? The wording has not changed since the 2016 version of the DOM Parsing and Serialization standard [0]: > On setting, the following steps must be run: 1. Let parent be the context object's parent. [...] 4. If parent is a DocumentFragment, let parent be a new Element with > - body as its local name, > - The HTML namespace as its namespace, and > - The context object's node document as its node document. But Blink instead throws a DOMException with name "NoModificationAllowedError" and message "Failed to set the 'outerHTML' property on 'Element': This element's parent is of type '#document-fragment', which is not an element node."
