I defined and used a tooltip in a FXML file as follows and when I check the tooltip in runtime, the tooltip is there but the id is missing!

------------------
  <fx:define>
<Tooltip fx:id="providerNumberTooltip_TT" text="Provider Number33"/>
</fx:define>
    <Label text="Provider Number:" fx:id="providerNumber_c_LB" tooltip="$providerNumberTooltip_TT"/>
---------------
control.getTooltip().getText() -> "Provider Number33"

control.getTooltip().getId() -> null
