Summary: This is a lighter UI treatment for previous/forward comments, where the comment is just hidden behind a click. This mayyy be too hard to discover, but I'd rather wait and make it more obvious if actually needed. Once you understand the interaction, the cleaner UI is preferable. Ref T7447
Test Plan:
Test a lot of previous and forward comments.
