Title: DOMPurify Improper Neutralization of Input During Web Page Generation (Cross-site Scripting) Vulnerability

Cure53 DOMPurify before 2.0.17 allows mutation XSS. This occurs because a serialize-parse roundtrip does not necessarily return the original DOM tree and a namespace can change from HTML to MathML as demonstrated by nesting of FORM elements.
