Tagging nested itemize with interaction

Tagging nested itemize with interaction

[Christoph Reller]

Dear Hans,

Consider the following MWE with nested multi-column itemize and item label:

\setuptagging[state=start]
\setupinteraction[state=start]
\starttext
\startitemize[n]
\item[label] First
  \startitemize[a, columns]
  \item Second
  \item Third
  \stopitemize
\stopitemize\crlf
Bla \in{Item}[label].
\stoptext

The above results in a PDF whose tag tree looks as follows:

‹document›
 |-‹itemgroup› itemize
 |  |-<item>
 |  |  |-‹itemtag›
 |  |  |  '-"1."
 |  |  '-‹itemcontent›
 |  |     |-"First"
 |  |     '-‹itemgroup› itemize
 |  |        |-‹item›
 |  |        |  |-‹itemtag›
 |  |        |  |  '-"a."
 |  |        |  '-‹itemcontent›
 |  |        |     '-"Second"
 |  |        '-‹item›
 |  |           |-‹itemtag›
 |  |           |  '-"b."
 |  |           '-‹itemcontent›
 |  |              '-"Third"
 |  '-‹link›
 |     '-"Item 1"
 |-"Bla"
 '-"."

In this tag tree, the ‹link› item is placed wrongly inside the topmost
‹itemgroup›. It sould be located between "Bla" and ".". This happens
only if:
1. An itemization with multiple columns is nested in an itemization
2. Interaction is enabled.

I think this is a bug. Please consider fixing it.

Kind regards,
Christoph
