ToolTips not finding method "getListeners" in scene2D Actor

[NullsByteBack]

Example taken from Wiki.

gdxVersion 1.9.12
vis-ui 1.3.0
Windows 10 x64

Also occurs in a blank project - can anyone else verify this?
Code:

	VisLabel label = new VisLabel("Some Label");
	new Tooltip.Builder("this label has a tooltip").target(label).build();
