Highlights touch vertically

SUMMARY
As the attached screenshot shows, there's no vertical margin between adjacent highlights. This is especially visible when having "Favorites" selected while hovering over "All applications". 

1. Select "Favorites"
2. Hover over "All applications"

OBSERVED RESULT
Both highlights touch each other

EXPECTED RESULT
A 1px or 2px gap between highlights

This is essentially the inverse of Bug 487653. Here we don't have the issue, but at the cost of touching highlight for adjacent items.

I'm not sure how possible it is to generically fix both issues until we've got Union styling everything.
Comment 3 Nate Graham 2025-10-21 19:41:19 UTC 
Actually, it looks like I can put in a local workaround for Kickoff, since list views in Plasma are still largely hand-made rather than standardized the way they are in QML-based apps and System Settings pages.

applets/kickoff: add spacing between non-switch-on-hover category items

Otherwise, their highlight effects touch, and it looks bad.

To avoid blowing up the layout as a result of this change, slightly
decrease the height of these category list items too, which also reduces
some code complexity.
