The stats bar that shows when you hover over community ads should be completely hidden until hovered over, but you can still see half of the bar below the ad:
The problem is that the space around the ad is created with padding and overflow: hidden; only hides content outside of that padding:
It would be an easy fix (swap padding for margin) if it wasn't for the bottom border that creates that faux break in the sidebar. So either the padding needs to be moved to a different element or the border does.
