		Dropdown menus use the checkbox hack and require `input` and `label` elements.
		The `label` element functions as the "visual" button and is hidden from screenreader users (T325026)
		while the `input` element is the actual semantic button for toggling the dropdown.
		The `input` element will always have an `aria-label`, which will usually match the
		text inside the `label` element, unless an alternative label is provided via the `#aria-label`
		mustache template data.
