Talk page bottom with same category shown three times

I've inserted a category in the talk header, in a thread summary and in a single message: it works (the single thread isn't summarized actually and it looks so, but this isn't a big issue), but the category is shown three times.
This bug would be really annoying in the case of subpaged threads (e.g. subpaged village pumps with a page for each day with multiple threads in it, where every day and every thread is categorized, as e.g. in or, and where we will hopefully have transcluded threads, see ).
Example: see URL and attachment.

While this behavior is annoying right now, this is a design issue (e.g., how do we *want* it to behave?) so I am taking it.

Description of the current behavior.

A category added to a thread shows in two places:

  • At the bottom of the Talk page along with all other categories on that Talk page's threads.
  • On the individual thread's summary page.

Each time the category tag is added to a reply or a thread, it is repeated at the bottom of both views. The problem here appears to be that Categories on both views should be de-duped before display.

LiquidThreads has been replaced by StructuredDiscussions on all Wikimedia production wikis (except one, which will be done soon). It is no longer under active development or maintenance, so I'm re-classifying all open LQT tasks as "Lowest" priority.
