 * Alert groups are containers for a set of alerts. Alert groups can hold one or many alerts
 * inside of them with the expectation that all alerts will be of the same type. The exception
 * to this rule is the `loading` alert type, which will be displayed regardless of the type
 * of alert group containing it.
