Tested with the official 1.9.5 release and the latest 1.9.5+ build (6/23/2009), both behave the same. See screenshot.

When you choose "cornflower" them and the click on the "Turn editing on" button, you will see the "Assign roles" and other icons mis-aligned. For the "Search Forums" block it's even worse - the "Assign roles" icon would be cut off. Just a quick FYI
