What steps will reproduce the bug?

import { Writable } from "node:stream";

const nodeWriteable = new Writable({
  write(chunk, encoding, callback) {
    // pending
  },
  highWaterMark: 5,
  objectMode: false,
});
const webWritable = Writable.toWeb(nodeWriteable);
const writer = webWritable.getWriter();
writer.write(new Uint8Array(3));
console.log(nodeWriteable.writableLength, writer.desiredSize); // expect 3,2  actual 0,4

let promise = writer.write(new Uint8Array(3));

console.log(nodeWriteable.writableLength, writer.desiredSize); // expect  6, -1， actual  0,3

How often does it reproduce? Is there a required condition?

always

What is the expected behavior? Why is that the expected behavior?

I think writer.desiredSize should be equal to highWaterMark - odeWriteable.writableLength
Otherwise, after the Writable.toWeb() conversion, the buffer queue for the writable stream is expanded

What do you see instead?

none
