Reviewer guidance

How can a reviewer test these changes?

1. Open a channel with multiple nested folders
2. Rename a folder so that it's name is longer than 50 characters
3. Navigate to the nested folders and also try resizing the browser window size
4. Confirm that only the first navigation item is the channel name and if the folder title is too long, it should be truncated
