FPM - Add Custom Action - GeoMap - InitialPosition not working

[nimble-123]

Hi,

in the FPM Add Custom Action content in the GeoMap fragment there is a data binding for initialPosition property which is not working as expected. Initial position is always set to 0;0;0.

            id="Map"
            mapConfiguration='{
			"MapProvider": [{
					"name": "Openstreetmap",

            refMapLayerStack="DEFAULT"
            initialZoom="10"
            initialPosition="{customer/pos}"
        >
            <vbm:Spots id="_IDGenSpots">
                <vbm:Spot id="_IDGenSpot"
                    position="{customer/pos}"
                    tooltip="{customer/name}"
                    type="Success"
                />
            </vbm:Spots>
        </vbm:GeoMap>
    </VBox>
	<endButton>
		<Button id="_IDGenButton" text="Close" press=".closeDialog" />
	</endButton>
</Dialog>
</core:FragmentDefinition>

UI5 Docs say InitialPosition can only be set during initialization. So i think it wont work with data binding.
