drag-handle almost invisible in Adwaita-dark
The handle (.drag-handle) in Search view is hard to see with Adwaita-dark
Steps to reproduce:
- Open GNOME Settings
- Open "Search" view
- The handle (.drag-handle) on the left side of each row is barely visible
(I'd like to work on this myself, but currently I can't build Settings with Gnome-builder due to #828 (closed))
