In this program, I'm seeing data not read yet being logged. I was assuming reader.closed wouldn't get resolved until the program had read the data. I've read the spec and it saysclosed should be resolved after the queue of data is empty.

const rs = new ReadableStream({
  start(controller) {
    controller.enqueue(new Uint8Array(3));
    controller.close();
  }
});

let data = null;
const reader = rs.getReader();

reader.closed.then(() => {
  if (!data) {
    console.error('data not read yet');
  }
});

data = await reader.read();
console.log(data);

data = await reader.read();
console.log(data);
