> The dropdown of a Spark ComboBox is not closed when an item is selected from the dropdown
list if the selection triggers a binding that sets the "enabled" property of the ComboBox
to "true" (even though the property was "true" before since otherwise one could not have opened
the dropdown).
> This happens because the setter of the "enabled" property in the ComboBox class is directly
inherited from SkinnableComponent, which calls invalidateSkinState() unconditionally (i.e.
even if the new value of the "enabled" property is the same as the old value). I managed to
work around the issue by overriding the setter of "enabled" in my custom ComboBox class and
not calling the setter of the superclass if the old value is equal to the new one.
