It looks like JAWS only seems to be supported with aria-labelledby in this case, but NVDA does not provide support.
In some initial sleuthing, it seems like there may be a support issue with NVDA and the shadow DOM with aria-named attributes similar to what is outline in this post.
I'm not sure the best path forward, as it seems browsers and AT is still catching up to support with shadow DOM. Maybe we just account for JAWS here, and mention NVDA is out of scope? Otherwise there are some hacky loop holes, maybe using a live region? WDYT?
- Use an ARIA live region instead of IDREFs. (This is the same technique used by canvas-based applications, such as Google Docs.) This option is pretty heavy-handed, but I suppose you could use it as a last resort.
Yeah we might want to mention NVDA is out of scope until it catches up with shadow dom. The next best option would be aria-live but I don't think thats a great solution. |

Is the control actually labeled by the entire header? When I run this through VO it works but UX wise I'm not 100% sure it makes sense. The entire header includes icons, heading, and description. That's potentially a lot of content to label a control.

I think its just the title and icon.
