• Fix "Stacking order can only be calculated for elements with a common ancestor" error thrown by the document pointermove handler when the event target is removed from the DOM during dispatch. Detached targets are now treated as viable hit targets. - #771
• Fix Group and Grid setLayout() and Panel resize(), collapse(), and expand() validating against pixel-based constraints for the previous group size when called before the group's ResizeObserver ran (e.g. from an application's own ResizeObserver). - #770
