Cannot bind size then set font

[johantiden]

iconSizeProperty and fontSize seem indepentend but are not. If you bind iconSizeProperty and then try to set the font, you get an exception.

FontIcon fontIcon = new FontIcon("mdi2m-magnify");
fontIcon.iconSizeProperty().bind(new SimpleDoubleProperty(17));
fontIcon.setFont(new Font("Arial", 10));

java.lang.RuntimeException: FontIcon.iconSize : A bound value cannot be set.

	at javafx.css.StyleableIntegerProperty.set(StyleableIntegerProperty.java:82)

	at com.sun.javafx.binding.ExpressionHelper.fireValueChangedEvent(ExpressionHelper.java:80)

FontIcon extends Text, which makes it eligible for css styling. The css engine will try to set the font, and procudes this stack trace for me:

As a workaround I will opt out of binding and properties on Ikonli objects.
