+Previously, alert and confirm dialogs in {productname} were not announced correctly by some screen readers, such as NVDA. The dialogs had an empty `aria-label` attribute and lacked appropriate `aria-labelledby` or `aria-describedby` references to the dialog body content. As a result, screen reader users could not hear the message or question presented in these dialogs, making it difficult to respond to confirmation prompts or understand alert messages.
