/**
* Parses a string into an HTML document, sanitizes the document and

*
* The sanitizer is designed to protect against XSS when sanitized content
* is inserted into a different-origin context without an iframe-equivalent
* sandboxing mechanism.
*
* By default, the sanitizer doesn't try to avoid leaking information that
* the content was viewed to third parties. That is, by default, e.g.
* <img src> pointing to an HTTP server potentially controlled by a third
* party is not removed. To avoid ambient information leakage upon loading
* the sanitized content, use the SanitizerInternalEmbedsOnly flag. In that
* case, <a href> links (and similar) to other content are preserved, so an
* explicit user action (following a link) after the content has been loaded
* can still leak information.
*
* By default, non-dangerous non-CSS presentational HTML elements and
* attributes or forms are not removed. To remove these, use
* SanitizerDropNonCSSPresentation and/or SanitizerDropForms.
*
* By default, comments and CSS is removed. To preserve comments, use
* SanitizerAllowComments. To preserve <style> and style="", use
* SanitizerAllowStyle. -moz-binding is removed from <style> and style="" if
* present. In this case, properties that Gecko doesn't recognize can get
* removed as a side effect. Note! If -moz-binding is not present, <style>
* and style="" and SanitizerAllowStyle is specified, the sanitized content
* may still be XSS dangerous if loaded into a non-Gecko Web engine!
