PDF is [Sample lease contract 26.pdf](https://github.com/mozilla/pdf.js/files/1500985/Sample.lease.contract.26.pdf)

Steps to reproduce the problem:
I am using [https://mozilla.github.io/pdf.js/web/viewer.html](url) to preview pdf by opening the pdf.

now am searching for "**made is**" but its not showing in the pdfjs

and while selecting and copying pdf  text it has no space in b/w words

segments[segIndex].start = file.getUint16();
        }
        for (segIndex = 0; segIndex < segCount; segIndex++) {
          segments[segIndex].delta = file.getUint16();
        }
        let offsetsCount = 0,
          offsetIndex;
        for (segIndex = 0; segIndex < segCount; segIndex++) {
          segment = segments[segIndex];
          const rangeOffset = file.getUint16();
          if (!rangeOffset) {
            segment.offsetIndex = -1;
            continue;
          }
          offsetIndex = (rangeOffset >> 1) - (segCount - segIndex);
          segment.offsetIndex = offsetIndex;
          offsetsCount = Math.max(
            offsetsCount,
            offsetIndex + segment.end - segment.start + 1
          );
        }
        const offsets = [];
        for (j = 0; j < offsetsCount; j++) {
          offsets.push(file.getUint16());
        }
        for (segIndex = 0; segIndex < segCount; segIndex++) {
          segment = segments[segIndex];
          start = segment.start;
          const end = segment.end;
          const delta = segment.delta;
