Re: ACTION-2107: Precedence of aria-details over aria-describedby

That is true. However, we did not see the need for multiple descriptions. Also, if you change that it would be a normative change. 

Since both define a description, the reason for the precedence is that authors can hide aria-details content where they are not allowed to with aria-details - meaning it is accessible to everyone and not just AT users.  aria-details is intended to be shown.
