           Summary: AX: aria-expanded state not consistently announced by
                    VoiceOver
           Product: WebKit
           Version: Safari 14
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal

          Assignee: webkit-unassigned at lists.webkit.org

Currently VoiceOver only announces the aria-expanded state if navigating an ARIA tree using VO navigation. If you navigate using keyboard shortcuts implemented in JavaScript the aria-expanded state is not announced.


Repro steps:

(1) Start VoiceOver
(2) Go to https://codepen.io/toddlr/pen/MWbbree
(3) Use VoiceOver navigation (e.g. Control-Option-Right Arrow) to navigate to an expanded ARIA treeitem instance
(4) Observe VoiceOver announces the treeitem as "expanded"

In contrast, the aria-expanded state IS NOT announced when navigating using keyboard shortcuts implement in JavaScript. For example:

(1) Start VoiceOver
(2) Go to https://codepen.io/toddlr/pen/MWbbree
(3) Move focus to the ARIA tree instance using tab
(4) Use the up/down arrow keys to move focus to an expanded ARIA treeitem
(6) Observe the expanded state change IS NOT announced by VoiceOver
