This still happens if the data is not randomly generated.

import { Readable } from "node:stream";
import { buffer } from "node:stream/consumers";
import { createBrotliCompress, createBrotliDecompress } from "node:zlib";

const input = new Uint8Array(1000000);
const output = await buffer(
  Readable.from([input])
    .pipe(createBrotliCompress())
    .pipe(createBrotliDecompress()),
);
console.log(output.length); // 14
