// Test for:

// https://html.spec.whatwg.org/multipage/xhtml.html#xml-scripting-support-disabled,

// "If the parser was created as part of the XML fragment parsing algorithm,

// then the element's already started must be set to true."

//

// These tests create an XML document and parse a probe-string containing a

// script. Due to the "already started" clause in the "Parsing XML documents"

// chapter in HTML, these scripts should not execute.
