Noticed while testdriving a rhel8beta install:
The add vpn dialog looks very empty, with just a single button thats snuck right under the headerbar. Is this intentional ?!
Definitely not intended. The list seems meant to use all dialog space, but only does so with enough items (also in width). Should be told to fill its space.
There's https://gitlab.gnome.org/GNOME/gnome-control-center/merge_requests/648 awaiting.
The fix is in 3.28.2-12
