/* Uncommenting this line will fix the problem when using
   transitional doctypes */

    min-height: 7px;

JavaScript

/*
    
    Steps:
    
        1) Run fiddle as created (HTML5 doctype, no added CSS)

        2) Change doctype (see info panel on sidebar) to HTML
           4.01 Strict or XHTML 1.0 Strict and run. No change.

        2) Change doctype (see info panel on sidebar) to
           HTML 4.01 Transitional or XHTML 1.0 Transitional 
           and run. Caret-only button renders shorter.
        
    
    
    With an HTML5 doctype, the button group renders properly.

    With a Strict doctype (HTML or XHTML), the button group
    renders properly.
    
    With a TRANSITIONAL doctype (HTML or XHTML), the caret-only button
    renders at a shorter height.
    
    adding a min-height on the caret will fix this when using a
    transitional doctype
