Description
Per https://asciidoctor.org/docs/user-manual/#managing-images
...you can embed the images directly into the document by setting the data-uri document attribute.
We use encoded images for the "X-Pack" and "Edit_me" images (in https://github.com/elastic/docs/blob/master/resources/web/styles.css), so it would be nice to use this feature in asciidoctor.
Unfortunately, if I add an image like this:
:compat-mode!:
:data-uri:image::xpack-tag.png[X-Pack]
The image is omitted from the output of the current asciidoctor version of the documentation build.
However if I test Asciidoctor directly, it works as follows:
