I think we determined this was due to DOM hierarchy usage and that it can be fixed by making the group with aria-owns the sub-element of the tree item

Chris, This issue has been proven to persist, even when the group with aria-owns is a child of the treeitem that controls its expansion. I've created an update prototype (https://codepen.io/toddlr/pen/MWbbree) and you can see for yourself with the following repro steps: 1. Start VoiceOver 2. Go to https://codepen.io/toddlr/pen/MWbbree 3. Use VoiceOver navigation to navigate the tree 4. Observe how VoiceOver will announce a group with aria-owns as having "0 items enclosed" Todd

Created attachment 420478 [details] Screen recording of the CodePen using Focus Navigation This example demonstrates how VoiceOver does not announce "0 items enclosed" when using keyboard shortcuts implemented in JavaScript: 1. Start VoiceOver 2. Go to https://codepen.io/toddlr/pen/MWbbree 3. Use the tab key to move focus to the ARIA tree instance 4. Navigate the tree using the up/down arrow keys 5. Observe how VoiceOver does not announce the ARIA group with aria-owns as having "0 items enclosed"
