Say I have a UI element that moves on the screen. Is it possible to update its accessibility frame as it moves while VoiceOver is focused on it? From my tests, VoiceOver ignores UIAccessibilityLayoutChangedNotification if it's sent repeatedly in a short period of time on iOS, while sending NSAccessibilityLayoutChangedNotification on macOS triggers VoiceOver to reannounce the focused element repeatedly.

While it is possible to scroll content using VoiceOver on macOS, I was not able to find any NSAccessibility APIs related to it (such as accessibilityScroll: on iOS).

On iOS, there is accessibilityLanguage.
