Ahh, I understand what you’re talking about now!

It’s a known thing.

You could try decreasing the padding-right to zero in your stylesheet so you can fit more activity comments:

div.activity-comments ul li {padding:10px 0;}

What would be nice is if the depth level of each activity comment was added in a class like [ul class=”has-comments acomment-depth-x”] where x is the activity comment depth level.
