Description

Observed behavior and steps to reproduce

When moving the camera, view annotations appear partially clipped, as if some invisible padding is applied

class MainActivity : ComponentActivity() {
    private lateinit var mapView: MapView
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        mapView = MapView(this)
        addViewAnnotation()

        setContentView(mapView)
    }


    fun addViewAnnotation() {
        val point = Point.fromLngLat(-122.4194, 37.7749)

        val viewAnnotationManager = mapView.viewAnnotationManager

        val resId = R.layout.test_annotation
        viewAnnotationManager.addViewAnnotation(
            resId = resId,
            options = viewAnnotationOptions {
                geometry(point)
                allowOverlap(true)
                allowOverlapWithPuck(true)
                ignoreCameraPadding(true)
                priority(0)

                annotationAnchor {
                    anchor(ViewAnnotationAnchor.CENTER)
                }

            })
    }
}

Expected behavior

View annotations must be completely visible within the camera viewport

Research direction

Start by reproducing the issue from the MainActivity sample with test_annotation on Android 16 and Maps SDK 11.15.2, then trace how view annotations handle camera padding while the camera moves. Done means the annotation remains completely visible within the camera viewport under the stated options.
