I'm not that confident, but if a screen reader performs the navigation,
then it can track the state, so that if the screen reader moved the user
somewhere, then it should be able to move it back without browser support.
Having said that, I'm not necessary argue against aria-details reverse
relation, but I would like to have a use case, where a screen reader would
be forced to traverse the whole document if it hadn't a reverse relation.
