`SymbolLayer`'s `symbolZElevate` does not work when `iconRotationAlignment` is `IconRotationAlignment.MAP

[xueyangp]

Environment

• Android OS version: 12
• Devices affected: Pixel 4A
• Maps SDK Version: 11.1.0

Observed behavior and steps to reproduce

When a marker (feature) is added in a SymbolLayer, with iconRotationAlignment(IconRotationAlignment.MAP) and symbolZElevate(true), the marker does not not render on the roof/top of a fillExtrusion

Expected behavior

I expected that the marker will appear on the top of any fill extrusion, regardless of the settings for iconRotationAlignment.

Notes / preliminary analysis

It appears not to work only when set to IconRotationAlignment.MAP When the iconRotationAlignment is not set(default), OR set as either iconRotationAlignment(IconRotationAlignment.AUTO) or iconRotationAlignment(IconRotationAlignment.VIEWPORT), the marker will correctly appear on the top of the fillExtrusion.

My code:

mapView.mapboxMap.getStyle { style ->
            val altitude = 2000.0
            val point = Point.fromLngLat(103.92979463782774, 1.1844947609581453, altitude)
            val circle = TurfTransformation.circle(point, 2000.0, TurfConstants.UNIT_METERS)
            val myCircle = Feature.fromGeometry(circle, null, "circleFeature")
                .also { it.addNumberProperty("altitude", altitude) }
            val geoJsonSourceFillExtrusion = geoJsonSource("circleFeature") {
                feature(myCircle, "circleFeature")
            }
            style.addSource(geoJsonSourceFillExtrusion)
            style.addLayer(
                fillExtrusionLayer(
                    layerId = "LAYER_ID",
                    sourceId = "circleFeature",
                ) {
                    fillExtrusionColor(Color.RED)
                    fillExtrusionOpacity(0.5)
                    fillExtrusionHeight(Expression.get("altitude"))
                }
            )

            val myMarker = Feature.fromGeometry(point, null, "myMarker")
            val myMarkerGeoJsonSource = geoJsonSource("myMarker") {
                feature(myMarker, "myMarker")
            }
            style.addSource(myMarkerGeoJsonSource)

            val marker =
                BitmapUtil.bitmapFromDrawableRes(context, R.drawable.red_marker)
            if (marker != null) {
                style.addImage("myMarker", marker)
            } else {
                Log.e(TAG, "Error getting myMarker bitmap")
            }
            style.addLayer(
                symbolLayer(
                    layerId = "MARKER_LAYER_ID",
                    sourceId = "myMarker",
                ) {
                    iconRotationAlignment(IconRotationAlignment.MAP)
                    iconRotate(25.0)
                    symbolZElevate(true)
                    iconImage(Expression.literal("myMarker"))
                }
            )
        }
