Default listing contains extraneous empty <a> tag in each item

[petrbouchal]

Bug description

In current pre-release, a default listing produces the code pasted below, which results in a slab of blank space at the top of each listing item.

Right below the tag, there is a

tag containing an empty tag. This results in an empty strip at the top of each listing item (reflecting the padding CSS setting for

tags).

This does not happen in the stable version.

<div id="listing-zacit" class="quarto-listing quarto-listing-container-default">
<div class="list quarto-listing-default">

Steps to reproduce

The listing is specified like so in the page YAML:

listing:
  - id: rizeni
    categories: false
    sort: poradi
    type: default
    include: 
      blok: "rizeni"
    fields: 
      - title

and inserted using

:::{.pruvodce-box}

::: {#zacit}
:::

:::

Only one file matches the include filter. On the same page, I have other listings with the same setup that multiple files and the same issues appears in them as well.

The one matches file is:

---
title: "Průvodce: kde začít"
blok: ['zacit']
poradi: 1
zacit: true
editor: source
aliases: 
  - /pruvodce/kde-zacit
---

Expected behavior

No extraneous tags with no content should be inserted.

Actual behavior

Each listing item contains an empty tag inside a

tag. If

tags have a non-zero padding param set in CSS, one ends up with a slab of empty space above the title of each heading item.
