Update: I managed to get RoundButton working. While it does only have a minimal frame, unfortunately (with non-Breeze themes I believe) the button seemed to be suffering from odd coloring issues such as randomly taking on highlight color (even when the notifications were not interacted with). Since I too now have little confidence in IconItem, I think the only thing we could do is make the existing ToolButton flat. But without the frame the icon looks too small.
