Additional Notes:

I wasn't sure how to test this change. The README gives commands for testing but they don't work. The only testing I did was run npm run start and click through the changed components.

It was confusing that the React package's README suggests using npm install but the base repo seems to have been converted to use Rush for dependency management.

Impacted Areas in Application

• TabContainer
• UtilityNav

I ran eslint --fix on the files I changed and it introduced several formatting changes -- let me know if you don't want those included. They seemed like improvements to me 🤷
