Research direction

Investigate the FlipperOkhttpInterceptor class in the Flipper Android SDK to understand how it intercepts network requests. The issue is in reactNativeFlipper.java where the interceptor is added via builder.addNetworkInterceptor(). Focus on how the interceptor might consume the response body or modify headers, breaking SSE's streaming behavior. Refer to OkHttp documentation on network interceptors and consider testing with a minimal React Native Android app using EventSource. Check if the issue was resolved in later versions of Flipper.
