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.

        transformBuf.length = 0;

          paddingBuf.push(`${divProps.paddingTop}px`);
          transformBuf.push(`translateY(${-divProps.paddingTop}px)`);
        } else {
          paddingBuf.push(0);
        }
        if (divProps.paddingRight > 0) {
          paddingBuf.push(`${divProps.paddingRight / divProps.scale}px`);

          paddingBuf.push(0);

          transformBuf.push(
            `translateX(${-divProps.paddingLeft / divProps.scale}px)`
          );
        } else {
          paddingBuf.push(0);
        }
