Ilya Buziuk has created a prototype of an HTML preview view with support of scrolling to the selected source element.
The prototype implements two main ideas:

1. It uses a self-written HTTP server to host preview pages. It allows to easily resolve resouces like <img src='../images/image.png'>.
2. It adds a custom attribute to the selected elements, to scroll to it (document.scrollTo(thatSelectedElementWithCustomAttribute))
