https://stackoverflow.com/questions/31584544/jquery-ui-dialog-on-resizing-shrinks-the-content-of-the-dialog

Fix:

resize: function() {
  var heightPadding = parseInt($(this).css('padding-top'), 10) + parseInt($(this).css('padding-bottom'), 10),
    widthPadding = parseInt($(this).css('padding-left'), 10) + parseInt($(this).css('padding-right'), 10),
    titlebarMargin = parseInt($(this).prev('.ui-dialog-titlebar').css('margin-bottom'), 10);
  $(this).height($(this).parent().height() - $(this).prev('.ui-dialog-titlebar').outerHeight(true) - heightPadding - titlebarMargin);

  $(this).width($(this).prev('.ui-dialog-titlebar').outerWidth(true) - widthPadding);
},
