**Expected behavior:**

```

Reproduisez le problème avec l’appel addMarkerSync et l’icône Base64 fournis, puis commencez par www/Map.js:1487, où le TypeError est signalé. Vérifiez l’entrée correspondante de commandQueueExecutor.js si nécessaire, et considérez le problème comme résolu lorsque le marqueur continue de s’afficher sans produire l’erreur width.
