We switched to using "bytes" streams but, by spec, chunks get transferred in that format. Totally reasonable. However, we pass reusable chunks which then get detached. I'm not sure why the polyfill or fixtures didn't catch this.

We really should be using the byob model instead and copy into a larger chunk for perf anyway so this just makes that more urgent.
destination.error(error);
  } else {
    
    
    
    
    
    
    destination.close();
  }
}
