Rendering Interactive HTML using Preact

It's possible to render HTML in Preact using the dangerouslySetInnerHTML prop, however doing so bypasses the Virtual DOM entirely. This may be reasonable for static HTML, but interactivity can be a little painful to graft on without VDOM.

There is another technique available that melds HTML to Virtual DOM without such limitations.

Enter DOMParser
