"No symbols found in document" when using include

[vvavrychuk]

Create include.adoc:

== H2 - include

=== H3 - include

Create test.adoc:

= Test

== H2 - test

include::include.adoc[]

Problem: "No symbols found in document 'test.adoc'` in outline

Commenting out "H2 - test" section header helps
