Comparison between linked buttons in breeze0gtk and adwaita
Buttons in a GtkBox with "linked" class appear as separate button instead of being linked. (This seems to be the behavior defined in https://invent.kde.org/plasma/breeze-gtk/-/blob/master/src/gtk3/widgets/_button.scss#L410). Ideally they should appear as a set of connected buttons.
STEPS TO REPRODUCE
1. Open Gtk3-widget-factory
Widgets such as comboboxentry do not appear as expected (with linked buttons) (see attachment)
Linked Buttons should appear connected
Breeze-Gtk-version: 5.22.5-0ubuntu1 (installed on Xubuntu 20.04 using deb package)
