This seems to be related to gsettings default values. On a freshly installed Groovy system using wayland, the snap-store is not properly themed. The window title bar appears to be using theme settings from bionic.
If I open gnome-control-center and select the appearance panel it immediately applies the proper theme. Something is triggering the theme setting to be updated there. It looks significantly better after themed properly.
