Describe the issue

According to the W3C tabs pattern: When a tab list has its aria-orientation set to vertical: Down Arrow performs as Right Arrow (moves focus to the next tab). Up Arrow performs as Left Arrow (moves focus to the previous tab). If the tab list is horizontal, it does not listen for Down Arrow or Up Arrow so those keys can provide their normal browser scrolling functions even when focus is inside the tab list.

These rules aren't supported by Boostrap 5 actually
