WhenState with factory function never gets stateValue

[evelant]

    const [activeState, setActiveState] = useFluidState(false)

    const whenFac: WhenFactoryFunction = ({ screenSize, metrics, state, stateValue }) => {
        console.log("State value? ", stateValue)
        return {
            interpolation: [
                {
                    styleKey: "transform.translateY",
                    inputRange: [0, 1],
                    outputRange: [0,  10],
                },
            ],
        }
    }

   const config = useFluidConfig( WhenState(activeState, whenFac))
   ....

In this example stateValue is always undefined when the factory runs regardless of the value of activeState

If I add a line activeState.value = activeState.active then stateValue gets passed to the factory function.
