Sphinx builds documentation but throws 126 warnings and not all HTML documents are rendered without artefacts

[HarmonicReflux]

Describe the bug

Building the documentation using Sphinx results in a "build succeeded", but I receive 126 warnings.

Also, there is a problem with artefacts in the rendered HTML files. For example, after the build succeeded, taking a look at the built docs/build/application-flow.html in Chrome browser, results in the screenshot displayed further below.

To Reproduce

1. Activate the virtual environment MUSE_OS is installed.
2. If necessary invoke sudo apt install pandoc
3. As per documentation 3.4.4. Building the documentation invoke python -m sphinx -b html docs docs/build

You should then see a screenshot similar to the ones posted below.

Expected behaviour

Building the documentation should run without warnings and rendering of the HTML documents should be without artefacts.

Screenshots

1. python -m sphinx -b html docs docs/build throws 126 warnings:

2. HTML document not rendered correctly:

Context

Please, complete the following to better understand the system you are using to run MUSE.

• Operating system (eg. Ubuntu 22):
• MUSE version: Recent development branch as of the time of writing. muse.version throws an error, so cannot specify the exact version as per the standard method.
• Installation method: Development mode.
• Python version (you can get this running python --version): 3.9.19
