/**
 * NOTES Concerning :visible prop.
 * Per W3C specifications:
 * https://www.w3.org/TR/wai-aria-practices/#alert
 * --
 * "It is also important to avoid designing alerts that disappear automatically.
 * An alert that disappears too quickly can lead to failure to meet WCAG 2.0 success criterion 2.2.3.
 * Another critical design consideration is the frequency of interruption caused by alerts.
 * Frequent interruptions inhibit usability for people with visual and cognitive disabilities,
 * which makes meeting the requirements of WCAG 2.0 success criterion 2.2.4 more difficult."
