That actually makes sense. In iOS and Android, in the traditional touch screen models, there is no concept of groupings. iOS later introduced a few container types such as tab bars and toolbars, and since iOS 15 or 16, people can also name other containers in their native apps, but both native field sets and ARIA group roles never had any effect so far in Safari or Chrome, and I don’t think Firefox on Android, either, because the API just doesn’t have a control type that matches that. In iOS, this could probably be implemented nowadays (see above), but it would obviously need to be done in WebKit.

@Marco That does make sense.
