Describe the bug

Warning: Can't perform a React state update on an unmounted component. This is a no-op, but it indicates a memory leak in your application. To fix, cancel all subscriptions and asynchronous tasks in a useEffect cleanup function.

setFocusedIndex @ Menu.context.tsx:34

Steps to reproduce the bug

  1. Open playground in storybook
  2. Click on one of the menu buttons rightmost in the table and then click outside to close menu
  3. now there is a warning in console. It only happens once, subsequent open/close menu does not produce warning until page is refreshed.
