/**
 * @description
 * Provides navigation inside the inner focus zone using Tab key
 * @specification
 *  Adds role='radio'. This allows screen readers to handle the component as a radio button.
 *  Adds attribute 'aria-checked=true' based on the property 'checked'.
 *  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 'data-is-focusable=true' based on the property 'checked'.
 *  Triggers 'performClick' action with 'Spacebar' on 'root'.
 *  Implements roving tabIndex.
