Currently, when selecting the Toggle Details buttons with a screen
reader like gnome-orca, nothing is spoken as the content after these
buttons in the DOM expands or collapses. I suggest adding the
aria-expanded attribute to all of these buttons. All of the collapsed
elements should be set to aria-expanded="false" and all of the expanded
elements should be set to aria-expanded="true". When the button is
selected by the user, the state of the aria-expanded attribute should be
changed as the content expands or collapses. This will cause the correct
expanded and collapsed notifications to be fired to assistive
technologies by web browsers.
