tableView does not properly handle a vgrow constraint being set upon it.

If I have a tableView in a vbox, then I should be able to add a vgrow constraint that will be processed by GroovyFX's layout constraint processing code. However, this code leads to an exception:

vbox {
  tableView(vgrow: 'always') {
  }
  ...
}

Caused by: groovy.lang.MissingPropertyException: No such property: vgrow for class: javafx.scene.control.TableView
