Comment (by afercia):

 There are a few more things to do here. The buttons: "Add a Widget", "Add
 a Menu" and "Add Items" are very, very, similar and should basically have
 the same CSS rules.
 Same for the HTML part, but here there's no need for an `aria-label`
 attribute to better specify the button's purpose. Also, no more need for
 `tabindex`.
 About the JavaScript part, buttons don't need a `keydown` event. We should
 handle the `aria-expanded` attribute and set proper attributes when the UI
 is in "reordering" mode, as done in the Menu Customizer.
