Label prefHeight vs wrapText

Sorry to dig up this old thread. Just wanted to mention a much simpler 
workaround if a label inside a vbox does not wrap its text:


As before the trick is to prevent vbox from reducing the label height 
below its pref height to preserve the wrapping - even if other children 
of the vbox need to be shrunk.
