If we take the example-manual.adoc document [from the maven example repo (
raw,
source on GitHub,
rendered with gist.asciidoctor.org)], I have noticed following difference:
Document compiled with maven:
[source,html]
----
<h2 id="source-code">Source Code</h2>
---
Document rendered with the browser live preview (Chrome or Firefox) or with gist.asciidoctor.org:
[source,html]
----
<h2 id="_source_code">Source Code</h2>
----
Why this inconsistency?
