        A DESCRIPTION OF THE PROBLEM :
        Using LSSerializer to pretty-print a DOM results in an xml-declaration being not followed by a newline.

        STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
        Run the following code.

        EXPECTED VERSUS ACTUAL BEHAVIOR :
        EXPECTED -
        <?xml version="1.0" encoding="UTF-8"?>
        <sometag/>
        ACTUAL -
