Bypassing DOMPurify with mXSS

Injecting the title tag is important because it mutates, as I’ve tweeted about in the past. In order for the mXSS to be effective I needed to inject the title tag outside of SVG as DOMPurify/Edge would correctly encode the HTML. I found you could use “x” as a self closing tag in DOMPurify and this would enable me to use the title tag outside of SVG
