	// Jest tests don't fail in some cases where we would see an error in DevTools
	// Console when running locally and we would also see the error in the test
	// output. This includes the React `Each child in a list should have a unique
	// "key" prop` error example.
	//
	// To catch this and fail tests in cases like this, we use `jest-fail-on-console`
	// to fail on calls to `console.error()`.
