Configuration:
- PDF.js version: 2.7.570

Steps to reproduce the problem:
1. Load the linked PDF
2. On the second page, highlight the word "Mitarbeiterinnen" by double-clicking it

What is the expected behavior?
The word should be recognized as a single word and highlighted as such.

What went wrong?
Instead, it's recognized as 3 words: "Mit", "arbei", "terinnen"

This happens for many words in this PDF.

Is there anything that can be changed in how I use pdfjs-dist to make it recognize this as a single word? Just looking at the PDF, I can't tell what would cause this behavior.

const fontHeight = Math.hypot(tx[2], tx[3]);
  const fontAscent = fontHeight * getAscent(style.fontFamily, ctx);
  let left, top;
  if (angle === 0) {
    left = tx[4];
    top = tx[5] - fontAscent;
  } else {
    left = tx[4] + fontAscent * Math.sin(angle);
    top = tx[5] - fontAscent * Math.cos(angle);
  }
  
  
  textDiv.style.left = `${left}px`;
  textDiv.style.top = `${top}px`;
  textDiv.style.fontSize = `${fontHeight}px`;
  textDiv.style.fontFamily = style.fontFamily;
  
  textDiv.setAttribute("role", "presentation");
  textDiv.textContent = geom.str;
  
  textDiv.dir = geom.dir;
  
  
  if (task._fontInspectorEnabled) {
    textDiv.dataset.fontName = geom.fontName;
  }
  if (angle !== 0) {
    textDivProperties.angle = angle * (180 / Math.PI);
  }
