Is this a full implementation of AsciiDoctor specification? Source code syntax highlighting and reference from outer source file with the "include::shared-content.adoc[]" syntax don't work for me.

doesn't work on chromebook for drive files. It also doesn't render a left side TOC, not sure why. And local images aren't showing up. If I run in linux on the same chromebook, it works.
