Polyfill for the Sanitizer API specification.
The polyfill might provide a shim on top of DOMPurify, that mainly rewrites the specified configuration object into a DOMPurify configuration.
DOMPurify is more interesting than other libraries, as it relies on the current browser's HTML parsing behavior (it is built on top of the NodeIterator interface).
There's a Demo page that loads all of the polyfill scripts and then does nothing. By default, the polyfill will bail out if you already have a Sanitizer object defined. But that can be easily overridden by clicking the ¶.
