In PDF2: Select correct abbrev href target.

[simtind]

Description

Select glossref instead of topicref as target when evaluating abbreviated-form gloss entries in pdf transformation.

Motivation and Context

Currently abbreviated-form gloss entriy references raises error DOTX060W as reported in #2773 and #3431. This issue seems to have been introduced in #3210. This PR does not revert the changes from #3210, but rather fixes the indexing so the correct href'd element is selected.

A more thorough fix discussed in #2773 and #3431 would be to update the pipeline to decorate the elements with separate ids so they can be correctly selected in the xsl transform.

How Has This Been Tested?

• Tested on internal code base that manifested the issue.
• Also tested on reproducer examples provided in the issue tickets. -- The initial example from #2773, abbreviation-test.zip did need to add print="yes" to the glossref in glossary.ditamap -- Otherwise, all examples built successfully with the patch, and failed with DOTX060W without it.

Type of Changes

• Bug fix (non-breaking change which fixes an issue)

Documentation and Compatibility

None needed

This PR doesn't appear to have been merged and is waiting on someone to review. Can someone provide an update? We have writers asking to use abbreviated-form and I recalled seeing mention of problems here or in Slack.

@kirkilj, @simtind - I apologize, I did not see this PR when I submitted #4002 (which is a similar fix, although a bit more robust). The original issue should be fixed in DITA-OT 3.7.4 and this PR can be closed.

However, the testcase revealed a second issue, which I filed #4026 for.
