What risks do you see aside from JavaScript URIs? Yes, there's status bar spoofing and other tricks - but how to execute script?

Mh, mostly xlink:href...so that'll be covered with the attributes filter anyway, I assume?
Though I'm unsure about how DOMPurify (the DOM Parser) handles namespaces.

Removal of xlink:href is already in place.

Although I am tempted to lift that restriction. Why not allow xlink:href? Even @InsertScript's SVG XSS should be mitigated in case DOMPurify is present.
