            Bug ID: 201458
           Summary: AX: HTML select with optgroup allows for selection of
                    disabled options
           Product: WebKit
           Version: Safari 12
          Hardware: iPhone / iPad
                OS: iOS 12
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Accessibility
          Assignee: webkit-unassigned at lists.webkit.org

In iOS on an iPhone it is possible to select a disabled option within the picker if the options contain an optgroup.

For example, an HTML select with the following code will allow the user to select any disabled option within the list of options:

<select>
    <option>one</option>
    <option disabled>two</option>
    <optgroup label="group two">
        <option>three</option>
        <option disabled>four</option>
    </optgroup>
</select>

Options "two" and "four," though marked disabled, can be selected and will appear as chosen within the pop-up button when it collapses.

VoiceOver does not report the disabled options as dimmed (though they style visually as dimmed).

This issue does not affect iPad. Only iPhone's picker manifests the issue.
