Setting preferred Height for a Gauge does not seem to have any affect

I place a Gauge in a Grid layout, if I specify a preferred Height for Gauge (using .setPrefHeight()) then the grid height is increased, however the Gauge does not change size.

If however I change the Width, using .setPrefWidth, but do not change the height, then the height and width of the cell along with the Gauge will expand correctly.

I would think the behavior would be consistant.
