Body length cannot be reliably retrieved from the web. Reading the "content-length" value will return a meaningless value when the response is compressed, as reading will return uncompressed chunks in any case, resulting in a mismatch between the detected body size and the actual size returned by repeatedly calling read_response_body_chunk. Additionally, while "content-length" is considered a safe CORS header, "content-encoding" is not, so using the "content-encoding" to decide if "content-length" is meaningful is not an option either. We simply must accept the fact that browsers are awful when it comes to networking APIs.
