 * @specification
 * Adds role='button' if element type is other than 'button'. This allows screen readers to handle the component as a button.
 * Adds attribute 'tabIndex=0' if element type is other than 'button'.
 * Adds attribute 'aria-disabled=true' based on the property 'disabled'. This can be overriden by providing 'aria-disabled' property directly to the component.
 * Adds attribute 'aria-disabled=true' based on the property 'loading'.
 * Triggers 'performClick' action with 'Enter' or 'Spacebar' on 'root'.
