// You will see here and there some 'tabindex' attributes added to various HTML
// elements, and Im sure you will ask "Why? They dont serve any purpose, do
// they?". Well you are wrong. Webkit has a **terrible** implementation of
// `:focus-within`, and the dropdowns will **not** work unless the parent
// element, in this case a `<li>` has a `tabindex` attribute set to `0` and its
// first child set to `-1`.
//
// Screw WebKit, and screw Apple for using such a terrible web engine.
