#32819 added `aria-describedby` to associate help texts and errors with
their inputs. I recently learned that there is also the more specialized
[aria-errormessage](https://www.w3.org/TR/wai-aria-1.2/#aria-
errormessage).

I am not sure if using `aria-describedby` over `aria-errormessage` was a
conscious decision.

One issue might be that `aria-errormessage` seems to be intended for
client side validation. It must be used with `aria-invalid="true"`. See
also https://github.com/w3c/aria/issues/2048 for a discussion of the
differences between `aria-describedby` and `aria-errormessage`.
