Markerview anchor attribute not working

[AymericIppon]

Describe and reproduce the Bug

Seems like anchor attribute is not taken into account and default value is kept.
The workaround I found is to use a state to update anchor value from a dummy value to the one I want after onDidFinishRenderingMapFully.

If I set the anchor value I want but display the MarkerView only after onDidFinishRenderingMapFully, the anchor is still centered.

I am using :

• "@maplibre/maplibre-react-native": "10.4.2"
• "react-native": "0.81.5"
• "expo": "54.0.25"

My fix :

export function BugReport() {
const [mapReady, setMapReady] = useState(false);

  return (
    <MapView style={{ flex: 1 }} onDidFinishRenderingMapFully={() => setMapReady(true)}>
      {Array.from(stops.entries()).map(([letter, coordinates]) => (
          <MarkerView
            key={`marker-${coordinates[0]}-${coordinates[1]}`}
            coordinate={coordinates}
            anchor={mapReady ? { x: 0.5, y: 1 } : undefined}
          >
            <PinIcon letter={letter} />
          </MarkerView>
        ))}
    </MapView>
  );
}

@tyrauber this works on iOS but is still broken on Android in beta-1.
