Worker does not work properly when the top property is filled.
I'm trying to extract the text vertically (top and bottom) instead of cutting it in the traditional way (left and right). With the exception of the last worker, everyone else cannot convert the image to text.

To Reproduce -RUN THE CODE BELOW

const { createWorker, createScheduler } = require('tesseract.js');
const path = require('path');


const scheduler = createScheduler();
const worker1 = createWorker();
const worker2 = createWorker();

const rectangles = [
  {
    left: 0,
    top: 0,
    width: 1486,
    height: 334,
  },
  {
    left: 0,
    top: 334,
    width: 1486,
    height: 334,
  },
];

(async () => {

  await worker1.load();
  await worker1.loadLanguage('eng');
  await worker1.initialize('eng');

  await worker2.load();
  await worker2.loadLanguage('eng');
  await worker2.initialize('eng');

  scheduler.addWorker(worker1);
  scheduler.addWorker(worker2);


  const results = await Promise.all(rectangles.map((rectangle) => (
    scheduler.addJob('recognize', 'https://tesseract.projectnaptha.com/img/eng_bw.png', { rectangle })
  )));
  console.log(results.map(r => r.data.text));
})();

Expected behavior
An array containing the two halves of the extracted text was expected, but only the last half was extracted.
And this is not just a problem with 2 workers I tested with 4 to try to speed up the process and 3 of the 4 workers did not work. Only the latter worked properly.

Screenshots
In this image I removed the empty characters ("") and the line break commands (\ n), to improve visualization.
