border-radius for tooltips/popovers incorrectly affected by .input-append

Created by: joshdick

Elements that trigger tooltips/popovers, as well as child elements in popovers, seem to be incorrectly affected by the input-append class. These elements lose their top-right and bottom-right border-radius when their associated tooltip/popover displays.

Here is a jsFiddle that shows the issue: http://jsfiddle.net/gb2YN/

Reproducible with Bootstrap 2.2.2 in Chrome 24, Firefox 18.0.2, and IE9.

Doesn't appear to have been fixed in 2.3.0-wip yet.
