That is indeed the interaction that I meant and IIUC what Janina
termed "Escapable Structure".

Janina: I don't quite follow why what I suggested is a problem. Are
you taking the view of a person that is not interacting with the page
and therefore cannot press a button to go to the next element to be
read out? The way I see it is:

with @aria-describedby the screenreader will start reading out the
long description to you and you have to actively interrupt it and move
on if you don't want it.

in contrast, with @longdesc the screenreader mentions that a long
description is available and you have to actively press a button to
get it read out if you want it, then press another button to move on.

>From where I stand, they are two different means of interacting and
some people may prefer one over the other. I cannot in general say
though that one is better than the other. They both have their merits.

Where am I wrong?

Thanks for helping me understand.
