https://dequeuniversity.com/rules/axe/4.3/aria-required-children In order to make this work, I had to translate Bulma's style so it doesn't use `ul` and `li` anymore. The JS code had to be adapted, I also changed `button` to `tab` (seemed like a more relevant name) and added a `scrollIntoView()` on load the active tab is always visible.
