Adwaita.css: Pathbar active state polished.
The hover/active state on path bar items currently looks a bit unpolished.
The main issues are: The bounding box of the items touching the dividers. The rounded edges touching the edge of the container.
To fix this issue, we add a margin of 3px around it, and reduce the border-radius to 4px.
