AccordionPane doesn't grow when children have dynamic values

[czaas]

Repro: https://codesandbox.io/s/unruffled-curie-6jjdy?file=/src/App.tsx

Behavior: when nested child component grows or exposes new items the accordion doesn't grow

Expected behavior: when a nested child component changes I would expect the accordion pane to grow with it

Possible solution:

1. We can try and detect any changes when nested
2. We could add a prop to the pane and add it as a dependency to recalculate pane height
