It looks like it doesn't. Tabbing through elements to focus on a button with it applied doesn't bring the hint up automatically, which would probably be the best experience here.

Just bringing it up wouldn't be enough, though, it has to be announced to screen readers. Or it would have to have a non-interactive way to work for screen readers.

Reason I'm asking is that this is non-trivial, and takes time to verify with different browsers and NVDA and JAWS. Having dependencies solving these issues are great.

That's a good question, thanks! I didn't think about that, but, surely, this functionality should be added. I will try to research what would be the best solution for accessibility.
