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

if (op >= 0x71 && op <= 0x75) {
            n = stack.pop();
            if (!isNaN(n)) {
              stackDelta = -n * 2;
            }
          }
          while (stackDelta < 0 && stack.length > 0) {
            stack.pop();
            stackDelta++;
          }
          while (stackDelta > 0) {
            stack.push(NaN); 
            stackDelta--;
          }
        }
      }
      ttContext.tooComplexToFollowFunctions = tooComplexToFollowFunctions;
      const content = [data];
      if (i > data.length) {
        content.push(new Uint8Array(i - data.length));
      }
      if (lastDeff > lastEndf) {
        warn("TT: complementing a missing function tail");
        
        
        content.push(new Uint8Array([0x22, 0x2d]));
      }
      foldTTTable(table, content);
    }
    function checkInvalidFunctions(ttContext, maxFunctionDefs) {
