Background

Currently there are a few Inputs that already carry aria-expanded attribute to trigger a connected Menu, but the don't feature an ARIA role allowing for this attribute or imply this connection.

Proposal

Let's add role="combobox" to these inputs throughout our demos. From MDN article:

The combobox role is set on input that controls another element, such as a listbox or grid, that can dynamically pop up to help the user set the value of the input.
