When the content of a live region changes, the change is presented to the user based on the following rules:
- If no ancestor nodes have explicitly set aria-atomic, assistive technologies will present only the changed node to the user.
- If aria-atomic is explicitly set to false, assistive technologies stop searching up the ancestor chain and present only the changed node.
- If aria-atomic is explicitly set to true, assistive technologies will present the entire contents of the element.
