This test checks the behavior of the ariaNotify
API with mixed priority messages to test queue
behavior.
Setup: Use a screen reader (NVDA, JAWS, VoiceOver, etc.) or other assistive technology that supports the ARIA Notify API.
Instructions: Click the "Run Test" button and listen for the announced text from your screen reader.
A normal-priority "Loading..." message followed by a high-priority "Loading failed." message, both fired against the document.
Expected: Screen reader should announce "Loading..." at normal priority, then "Loading failed." at high priority. The high priority message should be prioritized in the queue.
