            Bug ID: 224582
           Summary: AX: `aria-activedescendant` doesn't work with a
                    standard "listbox" pattern
           Product: WebKit
           Version: Safari 14
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Accessibility

With VoiceOver running, go to the example at https://jsfiddle.net/upy3m6n7/3/ and place the cursor inside the "Editable text" field. Use the arrow keys to move through the options (the selected option will get a "selected" class and become `aria-activedescendant` of the "editor" textbox element).

Expected: VoiceOver will identify each option as it is selected and becomes the `aria-activedescendant` of the "editor" element (this happens in Chrome and Firefox).

Observed: VoiceOver reads out nothing as each option becomes selected; there is no indication that there is an active descendant. 

The spec clearly indicates that elements with "textbox" role and correct markup should roles should accommodate `aria-activedescendant` (see https://www.w3.org/TR/wai-aria/#aria-activedescendant, particularly item 2). FWIW, though, as far as I can tell, the above behavior occurs with any role applied to the "editor" node.
