Research direction
Start in AnnotationManager.java at initializeSourcesAndLayers and its onStyleLoaded callback, then trace the Style.addSource call shown in the report. Use the reported MapboxMap style-loading scenario to investigate the duplicate source; done means the reported CannotAddSourceException no longer occurs.
