    modalDialog: Remove the fade in buttons code
    
    Due to a typo, it never worked correctly. After a fix-up to the appropriate
    method, the behavior is suboptimal, as the buttons only fade in the first time
    the modal dialog is constructed. Just remove the fade-in behavior, rather than
    keeping this non-working code around.
