Description of the need
Fieldsets that are collapsible should follow the accessibility requirements: https://www.w3.org/WAI/ARIA/apg/patterns/accordion/. We've got <details> in core but the Form API still offers collapsible fieldsets.
Proposed solution
If the fieldset is set to collapsible it should have aria-expanded toggled.
