Using an .input-group-button with a .btn-large button in a .jumbotron is slightly offset in Internet Explorer. This is fixed by explicitly setting the line-height of the .jumbotron .input-group.
Tested in latest Firefox, Chrome and Opera -- the fix has no side-effects. Tested in Internet Explorer 8, 9, 10 and 11 -- the fix works for all versions.
The problem and the fix can be seen in the following JSFiddle: http://jsfiddle.net/4L6f3/
