commit 6f5787e9a70fb8a473b059cd0c430ff0bdb2f725

    Don't shift the datetime picker up if it would hit the bottom
    
    Shifting it up weirdly covers up the input and sometimes runs into
    z-index problems with the aileron menus.
    
    The datetime picker now extends past the viewport bottom and will push
    the page taller if it hits the page bottom.  This requires a short
    scroll, but is preferable to inconsistent and awful looking alignment
    otherwise.
