This is another basic example that uses a core 4X method to
convert a static element into a fully accessible one for both
screen reader and sighted keyboard-only users.
</p>
<p>
After the simulated button is rendered, activate Visual ARIA to
observe how the accessibility mapping for the element has
changed, plus use the keyboard by pressing Tab to navigate to
the button and see how this now works.
