Firefox will start supporting `ariaNotify` in release 150. 🎉

`ariaNotify` allows you to provide text that should be announced by a screen reader if available and activated. No more fiddling with live regions. No more fiddling with live regions! 💪

Is ariaNotify a thing in Safari?

Accessible notifications using `aria-live` or `role=status`, etc., aren't a straightforward task. Updating the DOM is hard to get right and anything but convenient.

That's why the Edge team proposes and trials a new DOM method — ariaNotify(). 😱

I like it!

ariaNotify API works!
Testing with a WCAG working example by @patrickhlauke.bsky.social, the video illustrates the messages being conveyed for an uploading document progress bar "0%, 15%, 35%, upload complete" This is captured by a small app I am building "ARIA Testify"
