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

let glyphsIds = "";
  let bias = 0;
  let range, start, end, codes;
  for (i = 0, ii = bmpLength; i < ii; i++) {
    range = ranges[i];
    start = range[0];
    end = range[1];
    startCount += string16(start);
    endCount += string16(end);
    codes = range[2];
    let contiguous = true;
    for (j = 1, jj = codes.length; j < jj; ++j) {
      if (codes[j] !== codes[j - 1] + 1) {
        contiguous = false;
        break;
      }
    }
    if (!contiguous) {
      const offset = (segCount - i) * 2 + bias * 2;
      bias += end - start + 1;
      idDeltas += string16(0);
      idRangeOffsets += string16(offset);
      for (j = 0, jj = codes.length; j < jj; ++j) {
        glyphsIds += string16(codes[j]);
      }
    } else {
      const startCode = codes[0];
      idDeltas += string16((startCode - start) & 0xffff);
      idRangeOffsets += string16(0);
    }
