"Document objects have a throw-on-dynamic-markup-insertion counter, which is used in conjunction with the create an element for the token algorithm to prevent custom element constructors from being able to use document.open(type, replace), document.close(), and document.write() when they are invoked by the parser. Initially, the counter must be set to zero."

We have FIXMEs comments but no throw-on-dynamic-markup-insertion counter and the calls are always allowed.
