Re: ACTION-1442: Draft spec text for aria-current and aria-currentfor

So do we need aria-current/aria-active at all having aria-activedescendant?
If the container is not focusable then aria-activedescendant would indicate
to current/active element. If it's focusable then it points to
active/focusable/focused element. If that's bad idea then I'm curious about
the difference between aria-activedescendant and aria-current/active within
focusable container, for example
<div role="listbox" aria-activedescendant="item1">
  <div role="option" id="item1">item1</div>
  <div role="option" id="item2" aria-current="true">item1</div>
</div>

Iirc on Windows you can deselect all items in single-select listbox and
have current/active/focused item only.
