WYSWIG Editor Undo Level is limited to 10

The undo history is limited to 10 items. Can this be made unlimited and/or configurable?

From historyplugin.java:
/**

• {@inheritDoc}
• @see AbstractPlugin#init(RichTextArea, Config)
  */
  public void init(RichTextArea textArea, Config config)
  {
  super.init(textArea, config);

// Register custom executables.
History history = new DefaultHistory(textArea, 10); // <-------------------- ?
getTextArea().getCommandManager().registerCommand(Command.REDO, new RedoExecutable(history));
getTextArea().getCommandManager().registerCommand(Command.UNDO, new UndoExecutable(history));
