The dropdown appears weirdly off-center:

I'm not sure if this is an artifact of how the actual select is smaller than the area between the status bar dividers, or an unavoidable side effect of using custom styling, or what... it almost makes me wonder if we'd be better off with a custom dropdown like the ones we use for code hints, context menus, the Recent Projects dropdown, etc.
