What’s the behavior in Deno when a response body mismatch its length with Content-Length header?

Really curious about if Deno truncates the body (even if is a ReadableStream) when this happens, I read about this at https://www.ibm.com/docs/en/ibm-mq/9.0?topic=headers-content-length-http-entity-header

Thanks!

Set or return the length, in bytes, of the body of the message.
