We used to compute response body size as resource.transferSize - resource.responseHeadersSize. Resource.transefrSize returns 0 for cached resources, so we were getting negative values in this case. The correct value to return is 0 as per HAR spec v1.2: bodySize [number] - Size of the received response body in bytes. Set to zero in case of responses coming from the cache (304).
