Could you please add a code comment here to explain how this condition results in the intended UX? For example:    ```js  // Clicking the Management breadcrumb to navigate back to the "root" only  // makes sense if there's a management app open. So when one isn't open  // this breadcrumb shouldn't be a clickable link.   ```    I'm making all of this up so the details of this might be wrong, but you get the idea. :)
