Your point is taken, but I disagree, there is no terrible UI when content is
accessible. If aria-describedby points to visible text, how does a sighted user
or a magnifier user track focus to the visible description. It will depend on
how aria-describedby is implemented here, like any other technique.

Well, using longddesc, the keyboard focus will land on the link that was
selected once the target dialog is closed, thus preserving focus. Technically,
I do not see any issue there, unless implementers have UI issues.
