Current behavior

Currently if we set expanded to true for the PanelBarItems and change the data not all items are expanded.

Expected behavior

All items should expand when the expanded prop is set to true and the data is changed.

Minimal reproduction of the problem with instructions

1. Open this example and notice how not all items are expanded: https://stackblitz.com/edit/react-wgcmrl-pbezfj?file=app%2Fapp.tsx
