Extra linebreak when autodoc-documented parameter has multi-paragraph output

[cmarqu]

I noticed that when autodoc produces multi-paragraph output in HTML, I get an extra linebreak between the parameter name and the description.
In the following example (which is only indirectly using PST via SBT), stacklevel looks fine, but name has the extra linebreak:

When I run sphinx-build with -vvv, I'm getting

[autodoc] output:
[...]
      :param stacklevel: Which stack level to add the generated tests to. This can be used to make a custom TestFactory wrapper.
      :param name: Passed as ``name`` argument to :func:`cocotb.test`.

                   .. versionadded:: 2.0
[...]

and the resulting HTML is

<li><p><strong>stacklevel</strong> (<em>int</em>) – Which stack level to add the generated tests to. This can be used to make a custom TestFactory wrapper.</p></li>
<li><p><strong>name</strong> (<em>str</em><em> | </em><em>None</em>) – <p>Passed as <code class="docutils literal notranslate"><span class="pre">name</span></code> argument to <a class="reference internal" href="#cocotb.test" title="cocotb.test"><code class="xref py py-func docutils literal notranslate"><span class="pre">cocotb.test()</span></code></a>.</p>
<div class="versionadded">
<p><span class="versionmodified added">Added in version 2.0.</span></p>
</div>
</p></li>

There should be some CSS that removes the extra linebreak.

As a side note, my PR sphinx-themes/sphinx-themes.org#157 could be taken for https://github.com/pydata/pydata-sphinx-theme/tree/main/docs/examples/kitchen-sink and would then show the problem in pure PST.
The current code is not exercising this autodoc feature: https://pydata-sphinx-theme.readthedocs.io/en/stable/examples/kitchen-sink/api.html

I forgot to mention, this is with both Sphinx 7.4.7 and 8.1.3, and also happens with sphinx-rtd-theme.

The CSS I have come up with so far is

dl.field-list.simple > dd > p,
dl.field-list.simple > dd > ul.simple > li > p {
    display: inline;
}
