Description of expected behavior and the observed behavior

Many relative links inside the Panel documentation are broken - they are being interpreted with a # in front of the relative path.

E.g. on this page, there is a sentence near the top:

For further layout and styling-related parameters see the [customization user guide](https://panel.holoviz.org/reference/layouts/Accordion.html#../../user_guide/Customization.html).

I'm not sure where the # is coming from - in the source code for this documentation, the links do not have #: https://github.com/holoviz/panel/blob/ad94551cfa5fc15c637d459748aeb8da340974e2/examples/reference/layouts/Accordion.ipynb?short_path=d69f44e#L31

All broken links can probably be found in the docs build logs.
