I'm using several functions to clone the DOM and insert it into an SVG <foreignObject>. This approach is now well supported across modern browsers, although <foreignObject> is still a rather primitive way to handle HTML and styles within SVG, which can sometimes lead to results that aren't fully precise in certain cases. To reduce the size, I created internal CSS classes to avoid repeating CSS properties, and I'm also using several caches to prevent re-cloning styles that have already been processed. There's still a long journey ahead, but I hope a plugin system will allow for more fine-grained control over all capture stages
