support for aria-braille* properties

[pkra]

The ARIA Editors' Draft proposes the aria-braillelabel and aria-brailleroledescription property, see also https://w3c.github.io/aria/#aria-braillelabel, https://w3c.github.io/aria/#aria-brailleroledescription.

These properties are on track for ARIA 1.3. Browser support includes Gecko, WebKit and Chromium. (See also the 1.3 overview issue w3c/aria#1331 for more links to various bits and pieces.)

It would be very helpful for the ARIA WG to know whether these may be supported.

It seems the two properties should be supported since JAWS 2024.2406.121 (via https://support.freedomscientific.com/Downloads/JAWS/JAWSWhatsNew, after selecting JAWS 2024).

However, I was unable to confirm support. E.g., https://codepen.io/pkra/pen/WNgpQbK does not behave as I would have expected it - aria-brailleLabel was ignored on both the image and button.

Is there an example that works? Then I could feed that back into the ARIA 1.3 process.
