--- Comment #7 from Todd Kloots <todd.kloots at gmail.com> ---
Verified this as fixed. The root cause was the repro example (https://codepen.io/toddlr/pen/XWrGrGV) didn't implement aria-selected per the spec (https://www.w3.org/TR/wai-aria-1.2/#aria-selected). 

Specifically, per the spec: "Single-selection containers where the currently focused item is not selected. The selection normally follows the focus, and is managed by the user agent."

So, if an ARIA tree uses aria-selected in a single-selection mode it needs to explicitly declare all unselected treeitems using aria-selected=false else VoiceOver will (per the spec) assume focus and selection are in sync.
