    // recommended a11y pattern which has `role="group"` on the group element with `aria-labelledby`
    // pointing to the label. This works for `mat-select`, but it seems to hit a bug for autocomplete
    // under VoiceOver where the group doesn't get read out at all. The bug appears to be that if
    // there's __any__ a11y-related attribute on the group (e.g. `role` or `aria-labelledby`),
    // VoiceOver on Safari won't read it out.
    // We've introduced the `inert` mode as a workaround. Under this mode, all a11y attributes are
    // removed from the group, and we get the screen reader to read out the group label by mirroring it
    // inside an invisible element in the option. This is sub-optimal, because the screen reader will
    // repeat the group label on each navigation, whereas the default pattern only reads the group when
    // the user enters a new group. The following alternate approaches were considered:
    // 1. Reading out the group label using the `LiveAnnouncer` solves the problem, but we can't control
    //    when the text will be read out so sometimes it comes in too late or never if the user
    //    navigates quickly.
    // 2. `<mat-option aria-describedby="groupLabel"` - This works on Safari, but VoiceOver in Chrome
    //    won't read out the description at all.
    // 3. `<mat-option aria-labelledby="optionLabel groupLabel"` - This works on Chrome, but Safari
    //     doesn't read out the text at all. Furthermore, on
