Hello,
I'm trying to understand how nested file inclusions with level offsets are processed. Here's my use-case:
'test.adoc':
= main title
include:parent-include.adoc[leveloffset=+1]
'parent-include.adoc':
= parent title
include:child-include.adoc[leveloffset=+1]
'child-include.adoc':
= child title
include:grandchild-include.adoc[]
'grandchild-include.adoc':
== grandchild title
(Note the 'leveloffset' attribute when including the 'child-include.adoc' file in the 'parent-include.adoc' one)
I would expect that these relative nested leveloffset would combine/accumulate and give the following output when processing the `test.adoc` top-level file:
<h1>main title</h1>
...
<h2>parent title</h2>
...
<h3>child title</h3>
...
<h4>grandchild title</h4>
...
But instead, asciidoctor 2.0.10 gives the following result:
<h1>main title</h1>
...
<h2>parent title</h2>
...
<h2>child title</h2>
...
<h3>grandchild title</h3>
...
as if the `leveloffset` attribute in the `include:child-include.adoc[leveloffset=+1]` macro in the `parent-include.adoc` file was ignored.
Is it the expected behaviour or is it a limitation or a (known) issue?
