Wifi listview elements have wrong styling and miss separator
Description
When the wifi list is loading networks, the entries in the list shuffle around but it seems they keep their styling from the first appearance in the list. This if fine for the second to single to last entry as they have the exact same style, but the first and last one have rounded corners and no separators at the top or bottom. I didn't really know whether this was a bug in Gnome Settings or libadwaita but since I've never seen this bug in other adwaita applications, I assume this is a bug in Gnome Settings.
Screenshots
Notice the missing separator between two of the networks. One of those two is either the top or bottom entry in the list which doesn't have a separator at the start/end. Also notice how eduroam is presumably one of the center entries as it doesn't have rounded corners (harder to notice in the picture).
Steps to reproduce
- Open GNOME Settings.
- Open the WiFi panel.
- Wait until the entries in the list reshuffle and sometimes the styling should be off.
