What steps will reproduce the problem?
Create and dispose goog.editor with monitoring instances as below.

goog.Disposable.MONITORING_MODE = goog.Disposable.MonitoringMode.PERMANENT;
document.body.appendChild(goog.dom.createDom('div', {'id': 'toolbar'}));
document.body.appendChild(goog.dom.createDom('div', {'id': 'editMe'}));
var myField = new goog.editor.Field('editMe');

/**
 * @param {goog.editor.Plugin} plugin The plugin to register.
 */
var registerPlugin = function(plugin) {
  myField.registerPlugin(plugin);
  myField.registerDisposable(plugin);
};

// Create and register all of the editing plugins you want to use.
registerPlugin(new goog.editor.plugins.BasicTextFormatter());
registerPlugin(new goog.editor.plugins.RemoveFormatting());
registerPlugin(new goog.editor.plugins.UndoRedo());
registerPlugin(new goog.editor.plugins.ListTabHandler());
registerPlugin(new goog.editor.plugins.SpacesTabHandler());
registerPlugin(new goog.editor.plugins.EnterHandler());
registerPlugin(new goog.editor.plugins.HeaderFormatter());
registerPlugin(new goog.editor.plugins.LoremIpsum('Click here to edit'));
registerPlugin(new goog.editor.plugins.LinkDialogPlugin());
registerPlugin(new goog.editor.plugins.LinkBubble());

// Specify the buttons to add to the toolbar, using built in default buttons.
var buttons = [
  goog.editor.Command.BOLD,
  goog.editor.Command.ITALIC,
  goog.editor.Command.UNDERLINE,
  goog.editor.Command.FONT_COLOR,
  goog.editor.Command.BACKGROUND_COLOR,

  goog.editor.Command.STRIKE_THROUGH,
  goog.editor.Command.REMOVE_FORMAT
];
var myToolbar = goog.ui.editor.DefaultToolbar.makeToolbar(buttons, 
goog.dom.getElement('toolbar'));

// Hook the toolbar into the field.
var myToolbarController = new goog.ui.editor.ToolbarController(myField, 
myToolbar);

goog.events.listen(myField, goog.editor.Field.EventType.LOAD, function() {
  myField.makeUneditable();
  myField.dispose();
  myToolbarController.dispose();
  var undisposedObjects = goog.Disposable.getUndisposedObjects();
  console.log(undisposedObjects.length);
});

myField.makeEditable();
