Best Practices Checklist

We're trying to move away from some deprecated patterns in this codebase. Please
check if your PR meets these recommendations before asking for a review:

• Any new files are using TypeScript (.ts, .tsx).
• Avoid propTypes and defaultProps in any new or modified code.
• Tests should use the helpers in src/testUtils.tsx (specifically initializeMocks)
• Do not add new fields to the Redux state/store. Use React Context to share state among multiple components.
• Use React Query to load data from REST APIs. See any apiHooks.ts in this repo for examples.
• All new i18n messages in messages.ts files have a description for translators to use.
• Avoid using ../ in import paths. To import from parent folders, use @src, e.g. import { initializeMocks } from '@src/testUtils'; instead of from '../../../../testUtils'

@ChrisChV Nice work!

👍

• I tested this: (Verified selection conditions)
• I read through the code
• I checked for accessibility issues
• Includes documentation

LGTM - just some minor questions / optional suggestions.

I'm also wondering if we should be storing the selected container in the URL (instead of the React state), so people can share links? Could be useful on courses with huge outlines.

Thanks, looks good!
