When setting vertical=true, the button group component should have only a "btn-group-vertical" class, not combined with "btn-group" as it is now, see http://getbootstrap.com/components/#btn-groups.
When btn-group is also set, there is a slight CSS glitch: the upper right border is not rounded! This comes from a CSS selector triggered by the btn-group class, which should not be applied to a vertical button group.
This is also visible on the demo page, see screenshot attached!
