#render_image(image) ⇒ Object

As of version 1.12.0 of Kramdown the block elements (div & figcaption) inside this html block will have it’s < > converted into HTML Entities when ever this code is used inside block level elements.

To resolve this we have a post-processing task that will convert this back into HTML (I know - it’s ugly). The way we could resolve this without ugliness would be to output only inline elements which rules out div and figcaption

This issue is not considered a bug by kramdown: github.com/gettalong/kramdown/issues/191
