htmldoc multiplies content in current version

[MartinKl]

Describe the bug
I am using htmldoc (config below) to render a table for a span that only occurs only once per document (covering all contained tokens). Nevertheless the table is rendered 5 times. In ANNIS3 it was rendered the correct amount of times (once). I'll provide a link to the corpus (internal).

To Reproduce

Steps to reproduce the behavior:

1. Import the corpus
2. search "document" (for example)
3. open the visualizer "edition"
4. scroll down

If possible, please provide the corpus data needed to test the behavior.
The ANNIS software developers can't access the corpus data of ANNIS server installations.

Expected behavior
Only one table should be visualized (as it used to be in ANNIS3)
