Code formatting with hyphen creates two lines

[WalterHof]

Texts formatted as code that contain a hyphen are displayed on two lines in the PDF. For example: zypper ps -s is the -s under the zypper ps. Everything is correct in the HTML output.

The code:

SuSE - ``zypper ps -s``
-----------------------

``zypper ps -s`` zeigt Dienste die neu gestartet werden sollen.

.. code-block:: bash
   :linenos:
   :caption: SuSE prüfen mit ``zypper ps -s``

    zypper ps -s

The PDF output:

You see 3 times where the -s is below zypper ps.

The HTML output is OK:

Environment:

sphinx: 8.1.3
sphinx_simplepdf: 1.6.0
weasyprint: 63.1
python 3.13.1
Windows 11

Any idea what I am doing wrong?
