The glossary navigation buttons do not work

[mlell]

(Reported via the "Report a problem" button on https://plantbreeding.github.io/brapi-ontology/glossary.html)

When opening said web site, and clicking e.g. onto the button called "A", nothing happens. When clicking on a number button, all number buttons vanish except "1".

Tested on Firefox 130.0 and Chromium 129.0.6668.42 on Arch Linux. Also tested after disabling all extensions.
