Description of the issue

This issue is now very old, is it worth adding aria-expanded to details to fix it in Frontend instead?

Hi @joelanman, thanks for suggesting this. We currently cannot prioritise looking into this, but one thing that came to mind regarding the solution is that we'd not only need to make sure it fixes the issue for VoiceOver and Safari, but also doesn't negatively impact users with other browser/assisitive tech combinations.

We did look into this and from some rough testing, it unfortunately didn't make a difference. The root problem however will be solved by https://github.com/alphagov/govuk-frontend/pull/5089
