Thanks for testing. Same for me, NVDA.

The issue, IMO, is that the container of the callout has `role=alert` but no accessible name (which could be `aria-labelledby` to the ID of the title of the callout)

Yeah as you noted, the inner content container's role is currently [alertdialog](https://searchfox.org/mozilla-central/rev/48e7e2c55bd0d8977ff4f581a3753bcfc4259b83/browser/components/aboutwelcome/content-src/components/MultiStageProtonScreen.jsx#507), unless otherwise configured.

A couple years ago, we used to set `role=alert` on the outermost container. This was when we used `<div>` rather than `<panel>` for the container, and callouts were exclusively in-content. This was removed later in bug 1790382.
