some http requests to remote are hanging when using remote container port forwarding

• VSCode Version: 1.66.2
• Local OS Version: debian 11.3
• Remote OS Version: debian 10.11 (node:16.14 image)
• Remote Extension/Connection Type: Docker
• Logs: -

Steps to Reproduce:

1. run server in container(node:16.14 image).

// server.js

const { createWriteStream } = require("fs");
const http = require("http");

http.createServer((req, res) => {
  req.pipe(createWriteStream("/dev/null")).on("finish", () => {
    res.end();
  });
}).listen(3000);

2. set port forward local:3000 <-> remote:3000.
3. run client in local with node v16.14.2.

// client.js

const http = require("http");
let count = 1;

for (let i = 0; i < 10; i++) {
  const req = http.request(
    "http://127.0.0.1:3000",
    { "method": "POST" },
    (res) => {
      res
        .resume()
        .on("end", () => {
          console.log(`${count}: ${res.statusCode}`);

          count += 1;
        });
    },
  );

  // from 64 * 1024 bytes, it began to exhibit freezing problem noticeably often.
  // in some cases, you may have to increase the size.
  req.write(new Uint8Array(64 * 1024));
  req.end();
}

if directly request with container ip(like 172.17.0.x), it has no problem.

Does this issue occur when you try this locally?: No
